False color LUTs have been available for a very long time and are been used in security x-rays all the time. Same thing could be applied in human medicine, but doctors are throwing a fit if you even suggest it, so I doubt this would be any different.

The idea is great, though, since we can distinguish color far more easily than gray scales. It will just be really hard to convince radiologists that this is the right move.

This isn’t just a LUT, they are using multiple X-rays at different wavelengths to get more information about the tissue. I have another comment that goes into more depth.

Airport x-rays are basically doing something very similar. Two tubes with different kV, get information about the density of the tissue and then assign color based on that. The x-ray itself does not actually register color is any way, so the title is more or less bullshit. They assign color based on the information registered by the detector, so it's not too far from a LUT.

And I disagree with the patient risk assessment in your other comment. Yes, it's more dose than regular x-ray and probably doesn't offer any benefit substantial enough to justify its use, but it definitely wouldn't be dangerous for patients and nobody loses their hair for an x-ray (unless that was just meant as a joke).

Ya, I was trying to figure out if this is a new tech or they are just coloring a CT with a fancy new AI?

"The CERN technology, dubbed Medipix, works like a camera detecting and counting individual sub-atomic particles as they collide with pixels while its shutter is open."

"Sub-atomic particles" throws me off. I now realize I am too dumb to know if X-rays are waves or particles. Otherwise, it seems like they just described what any camera does. But maybe to a new/higher resolution?

I looked through a few different sources and they're actually just using an algorithm to color the image. So the title is pretty much bullshit, since this is already possible. Looks like they've done it better than anyone and focused on giving real-life colors to the different tissue forms, but that is not what medical imaging is about. A radiologist wants contrast, not a pretty picture to show the patient.

No doubt the new technology is impressive and certainly the kind of thing that you expect in a sci-fi movie where they x-ray you and then have a movable 3D-model during consultation. To me, the more impressive part is the fact that it's 3D, but I couldn't find any specifics on the setup, exposure angle or exposure time.

X-rays are photons at specific wavelength/energy (between 5keV and 1MeV, IIRC), so they're both waves and particles.

It looks like a bit of both - a fancy new ultra-quality x-ray machine paired with an AI to declare what energy levels correspond with which type of tissues and generate a 4D image. There's pretty much no way for this to be anything else than a gimmicky name: the black part of an x-ray photograph is where the rays actually hit and wouldn't benefit much from being fun colors(your bones show up because they reduce the amount getting to the imaging plate).

Pretty cool. I wonder if this will ever make it's way into industrial radiography. I could see it being very useful. I used to work for an industrial radiography company. It's basically like quality control for welds at plants and pipelines and stuff. We'd X-ray the welds and make sure theyre within code and not too much slag or porosity and stuff in the welds, and if it was out of code, we would mark on the weld where they needed to fix it. Im kind of nerding out here but it's interesting.

It's already being used in a less impressive form using false color LUTs. Basically, you assign color values instead of gray scale values.

In the industry, it's all about money, though, so I wouldn't expect them to pick this up any time soon. Some are actually still using x-ray film...

That's what we used. Except we used gamma radiation from iridium-192 and had to carry the fucking "camera", which weighs like 50 pounds, in and out of dirt holes and stuff. For long pipeline jobs, they use "crawlers" now, which is an actual X-ray machine that drives along the line inside of the pipe and X-rays welds from the inside out. Really neat, and makes much better looking images on film than a radioactive source does.

I read articles about welding sometimes. Things are more interesting with colored pictures because I'm a little kid.

Nothing wrong with nerding. I like all science and especially useful tech so I'm right there nerding with you!

Now I'm searching x-ray pictures of welding. Nerding out is contagious, didn't you know that?

Edit: his nerd shit is pretty cool

Yep, thats exactly what it looks like. That chart is showing the different kinds of faults you can see in welds

I would like to see the films of a really bad back. This could be very interesting.

Yeah this had me thinking something along those lines. Had an xray of my knee and although my Dr didn't find any damage he mentioned that I had a pretty good case of arthritis that will affect me when I'm old.

What I'm wondering is if bruised or irritated bones will show up better, and if the bone around desiccated discs and nerve damage will show any signs on the bone.

The source is much more coherent and clearly understands what they're reporting on far better than whoever shat this out.

I would guess that it's simply a high-res digital x-ray being run through a deep neural network to artificially colorize the images

I am actually a software engineer who works on medical imaging equipment. There seems to be a lot of misunderstanding about the tech here - it’s not just normal X-rays and LUTs. What they did is use multiple X-rays, each at a different wavelength, in order to view different properties of tissue. Imagine it as taking a photograph under red light, blue light, and green light - things that might look the same under identical lighting conditions may actually have different spectral properties, a.k.a. metamerism. But different lighting lets us tell them apart.

Overall this probably won’t be too useful in a clinical setting because of the radiation a patient is exposed to. Multiple X-rays = multiple times the ionizing radiation dosage. This isn’t a big deal in single X-rays, but CT scans use hundreds of X-rays from different angles to reconstruct a 3D model of the subject. This technique would probably make you lose your hair if you did it on your head. I really hope whoever got scanned with a watch on was wearing a lead vest!

“Researchers say”

If I had a dime for every time a new technology by “researchers” came out that would give us a better scientific utopia I would be richer than a rothchild.
