Quick credibility check

It is easy to spot that Nanox' management is not familiar with this simple thing called the truth.  Here is a quick example.  Today's press release announces:

With [the RSNA 2020] demonstration, we brought X-ray technology, which had not seen material technological advancements since its discovery more than 120 years ago, into the 21st century.

But Nanox own technology white paper states:

Modern X-ray and the evolution of radiologic modalities started in 1913 by introducing tungsten filament to the cathode part of the “Coolidge” tube, which supplied far better reliability than the preceding technologies. Over a hundred years later, X-rays continue to be generated by electrons supplied by heating tungsten filaments. The history of radiology is the history of the “Hot Cathode” invented by Mr. Coolidge.

1913, by the way, was just 108 years ago.  And X-rays were discovered in 1895, according to the same paper.

So, which one is it?    Did X-ray technology see a material technological advance after the discovery of X-rays but prior to RSNA 2020, or not?  The white paper says, yes, in 1913, when the hot-cathode technology introduced by GE completely obliterated the cold-cathode technology that Roentgen used and that Nanox now pretends to use.  The press release says no way!  Which one (press release or white paper) should we believe?   Which one (Coolidge or Poliakine) advanced X-ray technology?

Update:  By the way, Nanox cannot say that this is a simple mistake or misunderstanding, as Nanox claims that the Chair of its Advisory Board is Morry Blumenfeld, who was a GE employee.
