While the title is disingenuous because it’s easy to misunderstand it’s actually very close to the truth. Xrays are just a very energetic form of light or electromagnetic radiation, above the spectrum of visible light. Until now we only measure the general brightness of the xrays, and osirix translates (even marginal) differences in brightness into different colors. This makes features of the same brightness easier to spot for a human. This new technique actually measures different wavelengths of the xrays on our detectors and since we call the different wavelengths in visual light "color" it's a good analogy to call them the same for xrays. It can differentiate different colors of xrays. This is really promising, nuances in chemical composition may lead to differences in opacity for different wavelengths.

Yes I wouldn't be so impressed with a colorized image if the source was just a regular x-ray. But my impression was that they were capturing multiple frequencies, so it was a lot of extra information to the image. I don't know anything about radiology but I'm always excited to see some progress.

> Patients can even download the lite version and review their own images. This causes radiology companies so much pain. How do you give the images to them when people don’t have CD drives anymore? How do you get them to understand that they aren’t jpgs? How do you get them to a stage where they can open the images (they usually don’t have a Mac)? And the final pain is the last call. “What’s the black thing in the back of the white bit by the edge? Is it cancer?”
