This is unfortunately not new. It’s not ’color’ it’s multi channel imaging. X-ray tubes produce wide spectrum of x-rays, these type of sensors are able to put different bands to different buckets.&lt;p&gt;Coloring is arbitrary and conveniently chosen in the example to look like visible wavelength response as if the patient was dissected. It does not work for more complicated anatomy and even in this case needs very likely post processing.&lt;p&gt;I wish we could have a peek inside the patient as if we had opened it up but this is not yet that.</text><parent_chain></parent_chain></comment><story><title>First ever color X-ray on a human</title><url>https://www.yahoo.com/news/first-ever-colour-x-ray-human-005837590.html</url></story>

It sounds like the chips are detecting the energy of each xray, which is equivalent to a wavelength, and that data is then used to synthesize a 3D image.</text><parent_chain></parent_chain></comment><story><title>First ever color X-ray on a human</title><url>https://www.yahoo.com/news/first-ever-colour-x-ray-human-005837590.html</url></story>
