This feels like a real black swan event to me. I guess I just assumed that black-and-white x-rays were as good as it gets, and that there wasn't any room for improvement. I've never even thought about the idea of a color x-ray. It's very exciting to see something that could change the entire field of radiology.

Oh nonononono please no, no black swan event. The highest voted comment in this thread is very right.

I've worked on an X-ray machine during my second internship as an embedded engineer (fantastic internship!). My task was to optimize the way images and colors are presented to the viewer, given the measured X-ray data.

What I learned there is that whatever is presented to you on the screen is _completely arbitrary_.

When you have can measure a higher range of X-ray frequencies, you have more room to play with the colors. What colors you actually assign to the data is _absolutely arbitrary_, and technology similar to this has existed for a long time.

Oh I see, yes it's a bit underwhelming if that's the case. I don't even know if "true color" x-rays would be very useful, but I was thinking that being able to view the actual color of the tissue might be useful, and could convey some information that you can't get from density.

This is an article with a few paragraphs that is sensationalizing what is available while showing a single photo. Let's not overdo the hype.

OsiriX (and others) have been rendering radiology imaging in color and 3D for quite a while.



Patients can even download the lite version and review their own images.

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.

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?”

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.
