I recently got a hold of the full set of images from a cat scan of my torso/abdomen. There seemed to be a real brain scan dataset used near the end of kewlers/mfx's 1995. I wanna use my data this in some interesting way.
I can 'visualize' it easily enough by displaying the stack of images alpha-blended, or I can convert the images into a 3d voxel field and do something interesting with that... maybe isosurface it or display voxels, my lungs would look awesome with that.

Are there any other demos that have used MRI/CT data? Does anyone have any ideas?

I have. Have a look at MIP - maximum intensity projection. In CT/PET combination.

Comedy option: 1995.

you could make a 3D texture out of it and then raytrace stuff into it...

GbND:

take a look of these minimalanimal prods:

- Jesus was a pouët glöpper
- Voxel Effect

Both are software rendering. JWAPG contains Visible Human Male head and walking feet from the same dataset.
Voxel Effect contains a CRT scan of a head, supersampled from 256^3 to 512^3 (trilinear interpolated) and then only the surface taken, radiosity illuminated and textured. (I developed a voxel only radiosity algorithm years ago)

I don't remember if I have more of these in my demos... not sure, but I have lots of umpublished stuff with crt and voxel data... it is fun.

But better than CRT is the Visible Human Dataset. Unfortunately permission is required in order to get and use that data. I can't tell you I have it nor I can't tell you I can give it to you.

please dont make visible human / korean the new duck.3ds!

I think I have some kind of 3d-scan data from when quisten busted his knee on snowboard somewhere... I always wanted to use it for a demo-effect, but never got around to doing it.

yay! multiple, serious, helpful responses! Thanks everyone. ^_^ Texel, I may contact you with some questions, if wp/gfx textbooks don't answer them.

cp: How about visible penis? It's a small dataset.

OMG voxel-lobster (301x324x56 data set ).

I have Xray scans of Procyon/UD-s broken elbow somewhere but they're only 2D... maybe if we make something forensic. :D

ah, okay, you mean medical 3d stuff - i thought you mean general medical pictures...

to say something useful as well:

I use a radiography of my hands during the making of this old intro (background in the last effect, only the right hand appears in the effect... but both hands are in the radiography).

Why settle for less than your own femur, you shitheel. Limp Ninja has oodles of medical rendering experience to make bit or pieces of.

I should have soon an MRI of my left knee! Yay!

This is close to the very meaning of "really putting yourself into the making of a demo".

i think there should be more demos with x-ray porn in it

Nutman, well well I have attempted that very project 3 years ago with fellow group members. The demo would've been called "tpolm's insides" ;)

i've got lots of scans, feel free to choose between shoulders or knees. drop a mail if it's interesting.

Personally... I think voxel/volume rendering is next big thing before true* 3D displays. There's a lot you could do with voxels that would be almost impossible to do with triangles. Atom based physics, 'real' erosion, much more realistic interaction between objects... in a decade or so, there will be practically no memory constraint. Hell... 512^3 stuff can be done pretty much in realtime now, and I remember being amazed by quake at 320x240..
