A Remedi for fake SOURCE, TUBE, CART, and ARC?

 A strange article appeared in the Korean press, supposedly written on April 18, but embargoed until 4 hours ago.  It appears to claim that Nanox may have invested about a $1 million in the Korean company Remedi, based on google translate.  The article mentions that Remedi makes a small hot-cathode x-ray tube and a generic handheld dental medical device that has sold about 1,000 units since it started selling in 2017.  The device is similar looking and has similar specs as devices offered by other manufacturers all over the world, including sub-$600 units from China.  

Remedi may have an FDA clearance, but clearly has to do a lot of work to gain a meaningful share in the world market.  Its website has numerous typos, such as

Hogh[sic]-Voltage Generator, or

Remex is the best provide[sic] diagnostic imaging.

Still, the device has better performance than the fake Nanox.CART, in addition to being battery operated, and can be cleared for the same (and more) indications with an addition of a very thin filter.  The existence of such low-cost portable battery-operated x-ray devices makes a device such as Nanox.ARC redundant, even if it were real (which it is not!).

So why would Nanox, which is supposed to have a superior cathode, tube and device technology, invest in Remedi, a dinosaur making hot-cathode tubes and single-source devices?

Update: According to Remedi's website, the company also makes some other x-ray components and systems, including dental detectors, micro and dental CBCT, and radiation therapy devices.

Update April 22, 2022:  Remedi's small hot-cathode tube that needs no cooling mechanism or rotational mechanics, with length of about 1.6 inch, if we believe this picture.

Update April 22, 2022:  A similarly-worded article by the same reporter in the same publication appeared in December, claiming the same 1,000 units, and so implying that Remedi has sold absolutely nothing in the past 4 months.

Update April 25, 2022: Remedi's small hot-cathode tube may be a fake.  A 2019 manual for the T100 device shown above states (page 31) that the device is using a regular Toshiba tube.

Update April 26, 2022:  Remedi's device sold for $4,800 in early 2019.

Update May 5, 2022:  There is a problem with Remedi's KA6 device, the dental device masquerading as a hand-held portable x-ray device. In violation of FDA rules, Remedi marketing materials claim the intended use includes chest, head, abdomen and extremities, yet the device is only cleared for extremities.  

The device uses a regular Canon/Toshiba x-ray tube, D-041SB.  According to Nanox 20-F filing, this device may be sent to the MSaaS customers instead of the fake Nanox.ARC, thus democratizing healthcare and propelling the universe.

Update July 13, 2022:  TechNer08827503@Twitter noticed that the Remedi device (the "dental" version, but same hardware) is quoted for $1,650 in Indonesia, however, the price quote has remained unchanged since at least September 2020, so it may not be real and/or reliable.

Update July 25, 2022:  The smallest commercial x-ray tube currently on the market is likely the disposable S700 (link) made by Xoft (a sub of ICAD:NASDAQ) with a diameter of just about 2mm and length 15mm, a hot-cathode water-cooled one used for radiation treatment (50 kV, 0.3mA).  Not much demand for it.

April Fool's Day

Nanox is laughing at its investors today.  About an hour ago, it posted a short promo on linkedin for the upcoming re-opening of the new Korean Fab (the opening of the same Fab that was celebrated with great fanfare in October, with many Israeli and Korean dignitaries present and wide coverage by the Korean media):

If you take a good look, you will see giant white dust balls flying casually through the clean room, mostly emanating from the lower left corner.

I am not sure whether the dust balls are supposed to symbolize electrons or photons, or just the "culmination of the founders' vision," but I am pretty sure the clean-room "operator" in the bunny suit is typing:  THE JOKE IS ON YOU on the white keyboard.

Happy April Fool's Day!

A breakthrough

The Chairman of Nanox Korea, a convicted felon, decided to update his Facebook profile picture on February 25th.

In the comments about it, he clarifies that this is not an image of his head: 

• 혈관조영된 skull phantom 을 90KV, 14mA, 50mS 으로 calibration 없이 실험실에서 날거로 촬영 [which Google translates as Angiographic skull phantom was taken raw in the laboratory without calibration at 90KV, 14mA, 50mS]
• Digital X ray source(spindle type electron emitter)

And then he states:

1년 반 고생한 보람이지. 이제 본격적인 시작. 자네도 바빠질거야,

which Google translates as:

One and a half years of hard work paid off. Now it starts in full swing. You will be busy too.

So, is this some kind of a breakthrough?  Does Nanox finally have a working x-ray source that can be used in medical diagnostic imaging?

Based on what the Chairman wrote, the answer is simply no!  How come?  Isn't 90 kVp, 0.7 mAs (implied from 14 mA x 50 ms ) good enough?  That's not much worse than a regular cheap and small dental tube (such as CEI's OX/90, for example) that one can get for less than $100 on eBay, no?

The real problem is with what the Chairman writes about the "digital" x-ray source.  He is not an art school dropout, like Nanox Chairman - he supposedly has an engineering degree and spent at least some of his life, while not in prison, handling chips.  So he knows, or must know, that there is no such thing as a "spindle type electron emitter."  He might have meant a Spindt-type electron emitter, but a US-educated "engineer," who is supposed to be responsible for manufacturing the company's core technology at a brand new Fab cannot make such a mistake (if the technology were real, and if any manufacturing were to occur in the near future).  Moreover, while the electron emitter, if it were real, may have been somehow viewed as "digital," the x-ray source itself, that is, the tube, is definitely not digital, as the x-rays are supposed to be generated by indiscriminate and uncontrollable smashing of electrons onto a metal target - nothing digital about that.

Valentine's Day surprise

Nanox surprised its fans with a nice Valentine's Day gift yesterday.  A red heart on a blue x-ray, together in a nice Facebook post:

When your days and nights are spent in the pursuit of developing innovative global health care solutions and working to reinvent medical imaging, days like today remind us to appreciate those who love us and give us the strength to carry on. Happy Valentine’s Day to everyone who pushes us forward. #healthcare #valentine

Could this be an image from the new Nanox.ARC, with automatic heart detection by Nanox AI?  Turns out, no.  The chest image is just a stock-photo montage, uploaded in February 2007 and probably taken much earlier.

The Facebook post was probably made to divert investor attention from the massive sales by Director Stone last year, revealed in a 13G/A filing a few hours later.  Typical Nanox!

Now we know

Now we know why Nanox issued that misleading press release on January 11. 

We also know why Nanox management held a hastily-arranged virtual briefing for its Korean audience on January 14, where the same old lies were repeated, but nothing of substance was announced.  Amir Ben-Shalom, Ph.D., described as the former(?) Chief Science Officer of Nanox, and whose name pops up in all the scams concocted by the former CEO Poliakine, reportedly opined:

it will not be long before FDA approval.

Here is why:

In a pre-market 6-K submission filed yesterday, Nanox revealed that its June 510k submission to the FDA was withdrawn on January 12.  With the withdrawal, Nanox effectively admits that the complaint in the class-action lawsuit had merit, that is, Nanox failed to disclose in June that

(i) Nano-X's 510(k) application for the Nanox.ARC was deficient;  (ii) accordingly, it was unlikely that the FDA would approve the 510(k) application for the Nanox.ARC in its current form;  (iii) as a result, Nano-X had overstated the Nanox.ARC's regulatory and commercial prospects

As a result, the stock hit a new all-time low of $10.70 yesterday.

On a side note, as an example of the nonsense that went on at the Korean briefing, let's take a look at two images:

Nanox still insists its Nanox.SOURCE chip is a FED:

But the 20-F filed by Nanox clearly states that the FED is a type of a failed display, not a chip or a cathode (page 59):

Our technology has its roots in field emission display (“FED”) technology. FED technology was originally developed by Sony with other technology partners, for television screens and monitors, offering a novel way of lighting screen pixels compared to traditional cathode-ray tubes that were based on a one-source electron gun beam. The field emission display innovation used multiple nano-scale electron guns to achieve a much higher quality image with significantly reduced motion blur effects. In 2009, after having invested substantial resources in the development of this technology for over a decade including through a joint venture called Field Emission Technologies, Inc. (“FET”), Sony ceased development of the project.

Since when is Nanox in the display business?

Here is another interesting image, supposedly comparing a phantom chest image generated by "existing x-ray" (top) with that by Nanox.ARC (bottom).  It exposes Nanox as a fraud.

How so?  First, if the bottom image is not from an "existing x-ray," then it follows Nanox.ARC does not exist.  Second, it shows that Nanox didn't even bother to license the cheap DICOM software used to show the images, and is instead using a "fully functional trial version."  Third, the timestamp of the "existing x-ray" chest image, "10/10/2021 17:31:15," exactly matches the timestamp of the supposed tomosynthesis image of a pelvis phantom generated by Nanox.ARC shown in a video from the RSNA 2021 deck, indicating that Nanox is using tampered DICOM files.

Update:  Dr. Ben-Shalom disappeared from Nanox "leadership" roster by mid August 2021.

Update:  In November 2019, Poliakine told a consultant that the "FDA approval" was expected in early 2020.  Oh, and 

Aiming to have 15,000 systems deployed globally by 2022.

Nanox is panicking

After the stock price hit an all-time low of $11.79 yesterday, the CEO of Nanox has decided that enough is enough and issued a misleading press release this morning.

The press release is titled:

Nanox Announces Issuance of American Medical Association New Category III CPT® Code for Its Coronary Artery Calcium Population Health Solution

It turns out, however, that the new CPT code has nothing to do with Nanox AI or detecting any coronary artery calcium.  Here is the long description of the code:

Quantitative computed tomography (CT) tissue characterization, including interpretation and report, obtained with concurrent CT examination of any structure contained in the concurrently acquired diagnostic imaging dataset (List separately in addition to code for primary procedure)

It is a generic experimental code for quantitative, not necessarily AI, analysis of CT images (remember, those expensive and hard-to-get images that Nanox.ARC is supposed to replace worldwide by "democratizing imaging" and "propelling the universe").

The pdf file with the new code was created on December 17, modified on December 28 (per metadata), and finally published on AMA's website on January 1 (per official schedule).

So that was more than a week ago.  Why wait until this morning to issue the press release?

All this in the middle of a formal SEC investigation for fraud.  

Very brave of the new CEO!  Or not.

How x-rays are generated

Here is how x-rays are generated, according to Korean-based Nanox promoters on Yahoo and Twitter:

We inform investors of Nanox who want to democratize global medical care with innovative technology. Flowchart of how to make an X-ray

1. Substance (object)

2. Apply heat, light, impact, etc. to the material (object) 

3. Heat, light, impact, etc., emit electrons from the received material (object) (electron emission or field emission)

4. When the protruding electron collides with an object, x-rays are emitted. depending on what 1 is here

※Double metal (mems) such as Nanox molybdenum or gallium

※Other company's carbon nanotubes (cnt)

Note that the above algorithm is written in English - it is not a translation. Here is it with a specific object, such as a cucumber:

1.  Cucumber

2.  Apply heat, light, impact, etc. to said cucumber

3.  Heat, light, impact, etc., emit electrons from the received cucumber

4.  When the protruding electron collides with another cucumber, x-rays are emitted.

Now you know how x-rays are generated, Gangnam style.

Update:  Steve @Yahoo makes a good point about the heat, and asks:

Are you finally admitting that the Nanox cold tube isn't cold after all? You're using the word "heat" when describing how to make x-rays, yet one of the values of the Nanox tube is that it's a cold tube and doesn't make any heat to make an x-ray beam. So are you admitting that the company has been lying this whole time?

Nanox investors were never told that a cold cathode can get quite hot.  A cold cathode simply emits more electrons than can be supplied by thermionic emission alone.

Update:  The author of the above algorithm has offered further clarification:

X-ray X-ray When electrons collide with an object, radiation with strong penetrating power (electromagnetic wave) is emitted. This radiation is called x-ray. Usually, a flow of high-speed electrons collides with a material, and at this time, short-wavelength electromagnetic waves are generated, which are called x-rays. It was first discovered by Wilhelm Roentgen in 1895 and is also called the Roentgen ship.

So, now we further learn that:  

1. You don't need high voltage to generate x-rays (just a few volts potential should provide enough energy for the electrons to generate x-rays when smashing into an object, such as a cucumber)
2. A Roentgen ship is a thing.

Update:  The author's rebuttal to my understanding of his x-ray generating algorithm is as follows, verbatim:

If you go to the RxR blog, 1. There are psychopaths in the world who compare objects (substances) to cucumbers. Is this common sense? RxR is not a citizen of a country with a public education. It cannot distinguish between conductors, insulators, and semiconductors.

저가 RxR과 대화해본 결과 결론은 RxR은전기전자의 기초를 전혀 모릅니다. 도체.부도체.반도체.전자방출.전계방출.전자.원자.핵 전기전자 기초를 모릅니다. 속지마세요 가짜냉음극도매상 이거나 무식한 공매도 하수인 입니다.

Update January 2, 2022:  Jeremy @Yahoo points out, correctly, that, 

if you apply enough heat and light to the cucumber you will surely get x-rays, also from protruding electrons hitting the relativistic cucumber. See xkcd's relativistic baseball.

I had foolishly failed to consider a cucumber that had been accelerated to relativistic speed prior to step 1, or the use of a small nuclear explosive device in step 2.  In either case, of course, Nanox.ARC becomes a single-use disposable device, and the patient never returns for another annual diagnostic check-up.

Nanox is hiring

Nanox is looking for someone to develop the first generation of its fake x-ray tube using the fake Nanox.SOURCE chip.

The job description is the clearest admission so far that all the tubes Nanox has shown over the years have been fake (I can count at least 8 different "generations" of designs so far).  And, of course, any submissions to the FDA claiming use of any of said Nanox tubes must have been fraudulent.

Update April 20, 2022:  Job opening is still showing in the Career section of Nanox website.  I just noticed that Nanox seems to be confused about its own chip.  It calls it MEMS in the job description, but MEMs in the responsibilities. Of course, Nanox.SOURCE chip is just fake, but even if it were not, it is not MEMS, as there is nothing mechanical about it.  And there is no such thing as MEMs (even though Nanox 20-F filing insists on it).  Another thing I noticed is that it mentions that the job will require trips to Europe, however, Nanox European partner in the cold-cathode x-ray tube development scheme seems to have developed cold feet instead, as CEI salespeople now tell prospective customers that CEI is not making any cold-cathode tubes.  Finally, it is no longer true that Nanox is manufacturing "the x-ray tube" - the new fake Nanox Fab in Korea that was supposed to finally start making tubes suddenly can't make them, even though it is "operational."  I guess Nanox really needed to fill that job opening...

Chest protocol, the transformation

Nanox has been diligent in blurring all protocol-related data from its infomercial and the six accompanying "procedures" videos.  It missed just one bit (8m:54s into the infomercial).

That looks like 90 kVp, 5.8 (or 5.6?) mAs, and 3? tubes for the chest protocol.

During the Business Update in August, the chest protocol looked like 60 kVp, 50 mAs, and 5 tubes (7m:27s into the webcast).

Nanox.Arc was submitted for FDA clearance in June.  

Presumably the device had established protocols and was working at the time, unless Nanox committed fraud.  

But Nanox.Arc was not working last week, as evidenced by the infomercial.

Update:  To be fair, Nanox admitted Nanox.Arc was a "concept device" last week, and a "future product" not yet "regulatory approved" in August.  So, it can't have been a working product in June, with its protocols in hand, when it was submitted for FDA clearance, right?

Update:  A chest scan has to be quick, to avoid blurring from heart movement or breathing.  Movement-related blurring is especially damaging in tomosynthesis reconstruction, unlike in CT.  The faster, the better.  A live human is not a phantom, and can't stay completely still for the duration of the seconds- or minutes-long Arc scan, even if the Arc were real.  A nationwide survey revealed that the exposure time for a chest x-ray is typically about 20 milliseconds, and lower than 10 milliseconds when a digital detector is used.  If the exposure time were 10 milliseconds, then 5.8 mAs translates into about 200 mA tube current (3 tubes) and 50 mAs translates into 1,000 mA tube current (5 tubes).   The Nanox.CART dental tube, that supposedly validated the Nanox technology, could do just 2 mA (per 510K summary) and only at significantly-lower 40 kVp, according to Nanox, and it still required "liquid" cooling.  Just another way of showing that Nanox.Arc is still a fake.

A departure

A 6-K is filed after hours.  Stock not moving.  That could change.

On December 3, 2021, Jung Ho Park, a member of the board of directors of NANO-X IMAGING LTD (the “Company”), informed the Company of his intent to resign effective December 6, 2021, and the Company accepted his resignation. Mr. Park informed the Company that he decided to resign to fully devote his time to his role for the SK Group following recent reorganization in the Group.  His decision to resign did not arise or result from any disagreement with the Company on any matter relating to the Company’s operations, policies or practices. 

Under the Investor Rights Agreement between the Company and SK Telecom TMT Investment Corp (“SKT”), SKT has a right to appoint another director to the Company’s board of directors to complete Mr. Park’s term of three years and SKT intends to appoint a successor to Mr. Park

Ok, but what about disagreement not related to the company's operations, policies or practices?  And why wait for the successor appointment? 

cropped from image by Julian Brandt

Update December 8, 2021:  The so-called "recent" reorganization was announced back in August, when Mr. Park's new role was set to commence on November 1.  Why did he wait until December 3?   The departure is also suspicious for another reason:  the Korean fab, supposedly established with the "support" (per Prospectus) of SK Telecom, was supposed to receive its final equipment in November and start pilot production in its new building next month.  However, the comprehensive equipment list, complete with inventory numbers, on Nanox Korea website does not reflect any recent equipment acquisition, and just talks about making chips for household appliances (with outdated, over 20-year-old equipment that was there before November).

Update #2 December 8, 2021:  Mr. Park was given 100,000 options, in exchange for his employer investing 1,250,000 shares at $16 a share in June 2020.  The options vested on a quarterly basis, 6,250 at a time.  Mr. Park has not exercised any of them (the last batch vested on the day he resigned, December 3, I guess), at least as of the date of the annual report, and at this point, he won't make much, even if he does.  His "successor," if ever appointed, is supposed to be given 62,500 options with the same $16 strike, if I am reading the Prospectus correctly - again, not very appealing.  All this pales in comparison with what Dr. Kim, the convicted felon formerly at SK Telecom and now at the helm of Nanox Korea, received.

At the same time the investment was made, Nanox and SK Telecom agreed to 

explore and engage in good faith to develop a definitive agreement within six months of the date of the agreement for the deployment of 2,500 Nanox Systems in South Korea and Vietnam.

which is quite bizarre, really, since SK Telecom is no distributor of medical devices or a healthcare provider.  The agreement was supposed to be in effect until the end of this month, but "may be extended."  Sure enough, now the definite agreement is not likely to be signed, with Mr. Park gone.  Interestingly, neither South Korea nor Vietnam require FDA clearance, so the current "delay" with the FDA is no reason for not signing the agreement.  Nanox CEO did promise that Nanox had all the stuff needed to complete at least 1,000 Nanox.Arc units earlier this year.  But, for some reason, Nanox does not want to make them or ship them yet.

Finally, the official stance by SK Telecom in September, 2020 that 

major investors had already verified Nanox's technology and recognized its potential, 

and that 

We [that is, SK Telecom] have thoroughly reviewed our technology and investment value internally, 

now seems quite ridiculous given the ongoing SEC investigation, the RSNA 2021 infomercial, the chips for household appliances, and the new all time low of $13.90 the stock hit on December 6, the effective resignation date.

Pivot, or the evolution of fraud

Nanox.Arc circa March 2020:

Sort of like Star Trek’s fictitious “biobed,” the Nanox.Arc could provide a full-body digital X-ray scan down to the cellular level. 

“Because it’s digital, it’s multispectral. You don’t need different machines to do different kinds of imaging,” says Poliakine. That includes mammography, CT, fluoroscopy and angiography, for instance.

Nanox.Arc circa January 2021:

Angiography is out.  Still hope for CT (aka axial imaging), fluoroscopy, and maybe, just maybe, mammograpy (aka breast tomosynthesis)?

Nanox.Arc circa December 2021:

Fluoroscopy and mammography are out.

What is it that remains?  Axial imaging?  But Nanox.Arc can't do that either because it supposedly has just 5 tubes, not the 11 in that slide.

On the shapeshifting ability of skeletons

So, Nanox is showing a pelvis scan in its infomercial.   Things go well, until this happens at 13m:02s into the video.  

The pelvis phantom, with real human bones, has shapeshifted into an artificial skull.  But just for a fraction of a second.  Within a couple of frames, the skull transforms back into a pelvis phantom.

This is not an isolated phenomenon.  At about 13m:33s into the video, the pelvis shapeshifts into a hand.  The feet of the creature, alleged to be carrying a camera, move next to the patient table.  It is also revealed that the scout scan was never shown (a low-dose scout scan is often performed in real equipment making real scans to adjust the protocol for best image).

Conclusion:  Nanox.ARC is fake and did not make even the poor-quality tomosynthesis images shown by Nanox.  It is a mystery how those images were generated (and whether they were done manually or involved a robotic hand).  However, evidence suggests that it is possible that Nanox has discovered shapeshifters in our midst (luckily, no longer living).

Blurring timestamps to conceal time travel

There is interesting blurring in the Nanox infomercial.

For some reason, Nanox decided that it should hide the date/time the image was taken (October 10, 2021, 5:31:15pm, per DICOM data), but forgot to blur the same timestamp in the upper left corner.  Here is the unblurred timestamp from the hand scan video:

Why are timestamps important?  Because they reveal that the Nanox.Arc scan that supposedly generated that image never happened.  The timestamp was fake to begin with.  

Here is the supposed tomosynthesis stack generated by a pelvic scan.  The DICOM timestamp is again October 10, 2021, 5:31:15pm, to the second.  How come these two completely different scans finished at the exact same second?

What about the head scan?  That one is dated January 1, 2021 (no time shown).

But what about the Nanox.Arc scan that generated that hand image?  Did the scan actually happen?

According to the hand scan video, the scan took about 64 seconds (patient data is entered 00m:16s and scan finished 01m:20s into the video).

The problem is that the control pad (or the "operation console") shows something completely different - the scan took over 10 minutes, not just a bit over a minute, if it was done at all.  And it supposedly happened on November 22, 2021, more than a month after that blurred October 10, 2021 date, while involving an additional short jump back in time.

Here is the timeline of the hand scan, according to the control pad: 

4:44pm	Patient data is scanned (battery is at 37%, not charging)
	travel back in time 1 hour and 37 minutes, which drains the battery charge about 1/3
3:07pm	Select body region, protocol, prepare to start scan (battery is at 10%, charging)
3:13pm	Scan in progress, scan finishes, please wait for reconstruction to finish (battery is at 12%, charging)
3:17pm	DICOM preview, approved and finished (battery is still at 12%, charging)

Conclusion:  Nanox.ARC is fake and did not make even the poor-quality tomosynthesis images shown by Nanox.  It is a mystery how those images were generated (and whether they were done manually or involved a robotic hand).  However, evidence suggests that it is possible that Nanox has invented a time travel machine.

Update:  We were given a heads-up about the time machine in November:

 

Cold turkey

The price of a turkey in East Hampton, NY must be very high this year, so Mr. Richard Stone is selling (and probably already sold on November 19 to his broker) 200,000 shares of Nanox, cold turkey, at a value of $17.38 a share (according the the 144 form he emailed to the SEC).

This is about half of the shares he reportedly bought with cash on September 2019, pre-IPO.  His current holdings are a bit of a mystery, but the last 20-F states that he was a beneficial owner of a bit over 550,000 shares as of March 20, 2021 (includes options and warrants, outright and through intermediaries) 

Since the form was filed on November 19, a Friday, the stock lending/borrow fee has increased from about 7% to the current 57% (at Interactive Brokers).  It is not necessarily evidence of front running - when a large holder, who has lent his shares, sells, it typically takes a bit of time for the shares to become available to borrow from the new buyers.  The form was made public by the SEC on November 22, based on what I see in the webserver header.

Or just maybe Mr. Stone does not want to wait and see what will happen at the RSNA 2021 radiology conference next week.  See, Nanox started with a tweet like this in late October,

which has quickly transformed by the end of the month into this tweet:

 

What has Nanox never done before?  Tell the truth?

Mr. Stone is a Director of Nanox, and was a Director of Nanox predecessor since at least 2014.

Update:  In case it was not obvious, Nanox never traded below $18.30 a share as a public company, an all-time low it hit after Nanox disclosed a subpoena by the SEC on November 17.  Stock has fluctuated between that low and $20.57 since.

Update June 1, 2022:  Nanox filed a 6-K yesterday, stating:  "NANO-X IMAGING LTD (the “Company”) deeply regrets to announce that Mr. Richard Stone, a director of the Company, passed away unexpectedly on May 29, 2022. Mr. Richard Stone had served as a director of the Company since November 2019. Mr. Poliakine, the founder and chairman of the Board of Directors of the Company, commented, “It is with great sadness that we announce the passing of Mr. Richard Stone. He was a highly valued director of the Company and was an inspiration to all of us. Richard will be missed not only as a business colleague, but also as a friend and a true partner. We extend our deepest sympathies to the entire Stone family.”

Inflating the hedge

How does one know whether the market is approaching peak insanity?  Maybe it is the publication of an article like this.  The author argues that Nanox is a 

buy now and hold for the long haul 

stock because it is 

a way to hedge against runaway inflation.

That is completely nonsensical, of course, as Nanox has been telling investors that it plans to charge a FIXED fee per scan with its magical device, while its costs of manufacturing and other operating expenses will be subject to whatever inflation or deflation there is.  In other words, if Nanox were not a complete fraud, it would be the worst hedge against inflation.

The author gets the rest of the Nanox story completely wrong, too. 

With an efficient way to produce x-rays, 

But Nanox has never proposed an efficient way to produce x-rays.  Its proposed x-ray tubes, it they weren't completely fake, will be just as inefficient as regular x-ray tubes, as the inefficiency happens at the anode, not the cathode.

The author claims that 

Nanox.ARC produces x-rays with silicon chips that use modest amounts of electricity. 

That is quite interesting, because no functional Nanox.ARC device exists, at least none was demonstrated at the August Business Update and the recent AI webcast (Nanox has changed the design of the ARC supposedly demonstrated about a year ago at RSNA 2020).  Moreover, even if it existed, it would use the same "amounts of electricity" as a regular tomosynthesis device for the same (actually, worse) image quality, as the proposed Nanox x-ray source would use the same amount of electricity as the current regular dental x-ray tubes.  And, of course, x-rays cannot be produced with silicon chips, at least not commercially (Nanox claims to use molybdenum in its proposed chip, which happens to be fake).

Finally, the author confuses Nanox.CART with Nanox.ARC and FDA approval with FDA clearance.  Nanox has never shown a picture or photo of Nanox.CART, the only Nanox device that has been cleared by the FDA (and even that clearance appears a result of fraud by Nanox, based on what can be glimpsed from the published 510k Summary).  Also, FDA approval is completely different from FDA clearance under United States law, and claiming FDA approval when a device has been cleared is illegal.  Nanox has never submitted Nanox.ARC for FDA approval (or at least it never told the public about it) - it claimed in a June press release that it had submitted it for clearance only.

The single source Nanox.ARC has already been approved by the FDA, but the company's first attempt to earn approval for a multi-source device didn't work out.

I also have an issue with the archaic term used for CT,

Computer-aided tomography,

but that's probably a topic for another post (simplistically, the key difference between the old tomography, now called tomosynthesis, and CT is that the former can't do axial slices).  Needless to say, the proposed Nanox.ARC is not a CT device but a tomosynthesis device, according to Nanox.  What is the difference?  CT has something like 10%-20%, and growing, share of the medical imaging market using x-rays, and is considered the gold standard in many if not most x-ray diagnostics scenarios, while tomosynthesis (other than specialized breast tomosynthesis, which the proposed Nanox.ARC cannot do) is never "usually appropriate," according to ACR, and has less than 1%, and declining, market share.  It gets worse - the "tomosynthesis" images that Nanox has shown so far have no diagnostics usefulness whatsoever.

To be fair, the author hedges at the end of the article:

A fuzzy timeline for resubmitting an application to the FDA for a multi-source device combined with a lack of revenue makes this an ultra-high-risk stock at the moment. Cornering the market for x-ray equipment could be so lucrative, though, that it's probably worth the risk.

Great visionary

I think the company's outgoing CEO should be revered as a great visionary.  According to today's press release, the company spent $665K in the September quarter on "Class-actions litigation and SEC matter." That was months ahead of the "SEC matter" subpoena received on November 8 (per results call today).  That is what I call a foresight!

The Division of Enforcement of the U.S. Securities & Exchange Commission (the “SEC”) has notified the Company that it is conducting an investigation to determine whether there had been any violations of the federal securities laws. The Company has been providing documents and information and has now received a subpoena from the SEC requesting that the Company provide documents and other information relating to the development cost of the Company’s Nanox.ARC prototypes, as well as the Company’s estimate for the cost of assembling the final Nanox.ARC product at scale.

But somehow the company forgot to tell us about all that in its November 11 press release.  The stock has been dropping on "no news" since that November 8 date, of course.

Nanox celebrates the International day of radiology

Nanox celebrates.  

That is, Nanox CEO lies again on his blog.

First, he admits that Roentgen used a Crookes-type tube, which is a cold-cathode tube, when he discovered x-rays 126 years ago. not a thermionic or hot-cathode tube, as he has repeatedly lied in the past.  Then he correctly states:

Not many people know this, but for over 100 years the technology for generating X-rays has not changed.

Exactly right.  In fact, no one knows that for over 100 years the technology for generating x-rays has not changed, because it has.  With the invention of the hot-cathode tubes, or thermionic-emission tubes, by GE in 1913, the market share of cold-cathode tubes declined to basically nothing.  Other sources of x-rays were discovered and invented as well, such as the radioisotopes and the synchrotron.

So it is not completely true that 

In any X-Ray machine, the rays are still produced by thermionic emission technology...

but it is completely false that 

... that requires massive heating to develop the X-rays.

because the tiny Christmas tree lights, say 0.4W each, are hotter than the "hot" filament in a typical x-ray tube.

The real heat comes from the inefficient way of generating x-rays in any x-ray tube, be it cold-cathode or hot-cathode.  Electrons smash into the target/anode and only less than 1% of the energy is converted into usable x-rays, while the rest gets wasted as heat.  Yet, it is not a bigger problem than using, say, a 200W incandescent light bulb.

The outgoing CEO continues to lie:

Nanox developed the Cold Cathode X-ray tubes that are much smaller, and as per their name emit X-Rays at room temperature, which leads to considerable energy and cost savings.

Nanox has not developed any functional cold-cathode tubes - they are all fake and bigger than the regular dental tubes they are supposed to replace.  Even if they were real, they would not emit x-rays at room temperature, because the anode temperature can reach 5,000 degrees Fahrenheit.  And, of course, cold cathode does not mean cold or room temperature, it just means electron emission above the emission by the thermionic effect alone. The proposed Nanox tube, if ever made functional, will not bring any energy and cost savings -  just the opposite, as evidenced by all cold-cathode tubes in the past characterized by poor and unreliable performance and short life.

Mr. Poliakine then contradicts himself:

But even before Coronavirus, most of the people in the world did not have access to medical screening because they couldn't afford it or are too far away from a machine and a doctor. Nanox aims to change this.

That is a complete lie, of course, but you should forgive him, as a con-artist has often other things to worry about than remember what he wrote in his own blog more than a year ago:

In Israel, as in practically every country in the world, we have a real shortage of testing kits. Lung scans on the other hand are accessible, cheap, and the results are immediate - a critical factor in patient outcomes and in preventing the spread of the infection.

Lung scans, in practically every country in the world, are accessible, cheap, and the results are immediate, wrote Mr. Poliakine.  Lung scans are some kind of medical imaging, no? Typically, using x-rays, no?  Even CT (as shown in his March 2020 blog post)? 

Join us in our journey.

Sure.

For educational purposes only

The latest tweet by Nanox shows that its device can teach first graders the concept of an analog clock.  It has no x-ray tubes, and is for educational purposes only.

Too bad first graders are not allowed to attend RSNA 2021.

Concerns about the outgoing Nanox CEO

He apparently tweeted this, and someone caught him:

The tweet is now deleted.  "Nanon" and "ARK." Is he now busier swindling the Israeli state?  Or did I misunderstand the source of those $40 million?

Update:  The "ARK," of course, is the CEO's Freudian slip regarding ARK Fund's Israel Innovative Technology ETF (ticker: IZRL) - ARK is required to hold Nanox stock, even though Nanox is a fraud.

Remember, remember

Remember that Bloomberg piece that Nanox tweeted in early March?

A forward-looking statement is typically a safe-harbor statement, but what if the CEO of Nanox, Mr. Poliakine, did know at the time that ALL the 25 ARC systems were fake and non-functional (the photo obviously shows fewer than 25 systems anyway) and that Nanox was not on pace to make and ship 1,000 units by the end of the first quarter of 2022 at the latest?

I mean, how can Nanox be on pace to ship those 1,000 systems, if they have no x-ray tubes and if he knew that the tomosynthesis reconstruction algorithms create images that may be useful for diagnosis of aliens, but not of humans?

How to tell that a clean room is not clean

How to tell?  Easy.  You look for the fake dust particles that the video editor introduces subconsciously in the video walk-down of  the fab and then posts that clip in the lowest-possible resolution on Youtube.

Alien lifeform discovered

Today's Nanox AI event showed a sample image from "nanox.Arc demo unit" that was not submitted for regulatory approval. 

Can someone explain what I may be seeing here - aren't there too many bones?  Was this early detection of an alien lifeform living inside a phantom human hand?

Update November 5, 2021:  The recording of Nanox AI event posted on Youtube has been made private and cannot be viewed anymore.  I wonder why.  Time to notify the FDA about the alien discovery by a device about to be cleared?

Update November 9, 2021: Recording is viewable again, under new URL.

Update November 14, 2021:  I was asked on Youtube how I can be sure that the June submission for FDA clearance was fraudulent.  Dr. Orit, the Chief Medical Officer, admitted during the webcast that 1) the Nanox.ARC device is currently under development (49m:44s), and the "images" [including the disastrous tomosynthesis slab of the "alien lifeform" hand] are currently not usable for diagnostic purposes - "it is still being developed" (52m:07s).  Therefore, the device submitted for clearance in June was not ready to be marketed or tested, which is fraud.

Language confusion

Nanox states in each of its recent press releases that 

Nanox ... is an Israeli corporation 

Surprisingly, its website lists only English, Korean, Chinese, and Japanese as available languages.  The country's official language, Hebrew, is somehow missing.

 

This is not an accidental omission.  The website of the CEO's related scam, DHI 2048, which describes itself as 

UAE-based organization 

is only in English, and has no option for Arabic, the official language of UAE.

Why is that?

Half and half

During the August 16 Business Update, which was supposed to show the latest and greatest by Nanox, Dr. Kim, a convicted felon, said:

... we are now manufacturing MEMS chips from our own facility [in Korea]

Turns out, they were not manufacturing MEMS chips in Korea, at least not in a finished form.

According to his latest interview, things are done half in Korea and half in Japan (just as the CEO had described during an earlier results call on August 11).

Here is the translation:

The [fake] chips are made in Japan [not in Korea]

we can't process wafers from beginning to end [in Korea] 

we don't have the equipment to do so

we just don't

so of the 100 [fake] wafer processes, 50 are 

done in Korea, then the wafers are 

sent back to Japan to do the remaining 50.  

Then a fake chip emerges and propels a magic Japanese x-ray tube to Israel, or something like that.

Update October 23, 2021:  While Dr. Kim's statements agree with the CEO's August 11 statements, they disagree with the CEO's statement during the August 16 Business Update.  Nanox CEO lied when he said that the chip was made in Korea - Dr. Kim said it was made in Japan (while only partially pre-processed in Korea).  One can argue that it does not matter, since the chip is fake, anyway.
