WHIS-RAD, WHO's alternative to Nanox Vision

Nanox Vision is a cancer-inducing initiative contradicting the ALARA principle and ImageWisely, as proclaimed in the joint June 2019 press release with SK Telecom: 

nanox.vision is the global initiative led by nanox and world-leading healthcare players to drive the 1x1x1 vision of at least one medical screening for each person on the planet each year. The 1x1x1 Initiative is based on nanox's revolutionary MEMs X-ray source and encompassing ecosystem of partners to provide affordable, early detection for all. 

Note that early detection has actually two separate components: 1) early diagnosis and 2) screening.

Nanox falsely claims in its prospectus:

We believe [heat and complexity] key factors leading[sic] to the high cost and complexity of existing medical imaging systems, which in turn significantly limits the availability of medical imaging for early detection globally. According to a report from the Pan-American Health Organization and the World Health Organization (“WHO”) in 2012, approximately two-thirds of the world population did not have access to medical imaging, while many people with access to medical imaging face substantial wait times for scanning.

What the WHO report actually says is:

The use of X-rays and other physical waves such as ultrasound can resolve between 70% and 80% of diagnostic problems, but nearly two-thirds of the world's population has no access to diagnostic imaging [not the same as medical imaging, see above]

Nanox fails to mention WHIS-RAD, WHO's proposed solution.  WHIS-RAD system was developed by the WHO in collaboration with radiographer experts.  It was designed to provide high-quality images and to be safe to use, reliable, easy and simple to learn. Additionally, it is designed to operate where power is unreliable or unavailable for extended periods of time.  So much for Nanox Vision!

"Providing low-cost, high-quality x-ray units was the goal behind development of the WHO's basic radiology system" (Alternatives to WHIS-RAD units fall short.)

WHO's purchasing guide states that the first imaging unit any hospital should buy is a general-radiography x-ray system like WHIS-RAD, which automatically eliminates both single-source and multiple-source Nanox.Arc, due to their low power and inability to do standard chest x-ray.  So much for Nanox conquering the world!

Recent assessment notes that the equipment works well and easily satisfies the requirements of the original design, and is adapted to the digital age, but notes some reasons for the low number of installations.  Cost is about $45,000-$50,000 (Radiology for the People: A Basic Radiological System for Health Care inDeveloping Nations, 2019)

Update March 26, 2021:  Arsakaan @ Twitter reminded me again why Nanox should not be allowed to market/promote ANY medical device.  Nanox is not just some investment fraud - with its incompetence, it endangers lives, even if it has no intention to ever shipping any working device.  The snapshot from the current Nanox webpage still shows this overlay:

Of course, anyone remotely familiar with cancer screening should know that "cancer screening is looking for cancer BEFORE a person HAS ANY symptoms."   That is, screening SYMPTOMATIC patients is non-sense.  Moreover,  the U.S. Preventive Services Task Force does not recommend any plain X-ray, fluoroscopy, or tomosynthesis (what Nanox claims will be offering with the Nanox.Arc it intends to commercialize) as a screening tool today - only mammograms for breast cancer (only for women aged 50 to 74 years) and low-dose CT for lung cancer (only for adults aged 50 to 80 years who have a 20 pack-year smoking history and currently smoke or have quit within the past 15 years; screening should be discontinued once a person has not smoked for 15 years or develops a health problem that substantially limits life expectancy or the ability or willingness to have curative lung surgery).  Nanox.Arc, as designed today, cannot do either mammograms or CT, of course.  That is, Nanox.Arc is useless for screening purposes.

Update May 20, 2021:  added a link to screening definition from the U.S. Department of Health and Human Services.
