To the best of Nanox knowledge

Nanox (and predecessor) "first" press releases are quite amusing - Singapore detector in October 2013, digital 1x1x1 in June 2019, and the field of cones, November 2019.

So, Mr. Masuya, a lawyer and the founder and CEO of Nanox predecessor, says in November 2019:

to the best of our knowledge no company have achieved a commercially stable [cold cathode] source [based on carbon nano tubes] that can be embedded inside a medical imaging system and operate with an acceptable lifespan. 

The problem is that he must have known that Carestream and Micro-X had received clearance for and commercialized their Nano x-ray system with a cold-cathode source based on carbon nano tubes in February 2018.  That source was initially made by XinRay (a Siemens JV now defunct, but see NuRay), and now by Micro-X Ltd.  So much for Nanox "knowledge."

And where is that Nanox source that can be embedded inside a medical imaging system and operate with an acceptable lifespan?  Or did he mean a cheap underpowered hot-cathode Chinese source not suitable for medical imaging? 

Note:  High current with a maximum emitter current of 130mA for up to 2 seconds per tech page.  Compare to Nanox 11mA "proposed" hand-made "hight [sic]" chart. 

First digital source

 In its "first" press release issued in November 2019,  Nanox says:

Nanox, founded by the serial entrepreneur Ran Poliakine, is an Israeli/Japanese cooperation that has created the world’s first commercial-grade digital X-ray source for real-world medical imaging applications

How do you define digital? Roentgen used a cold-cathode (gas discharge) tube when he discovered X-rays, and so did all commercial X-ray sources until 1913.  Carestream/Micro-X/XinRay got clearance for the mobile x-ray unit that uses CNT tubes in February 2018.

Update March 31, 2021:  Vatech got clearance for its dental x-ray system that uses a CNT tube (V1-650304) in September 2016.
