I built a CT scanner from an x-ray tube that I bought on eBay, a stepper motor, a large ring bearing, and an Arduino. I used a phosphor screen and my camera to capture x-ray shadow images of a frozen chicken, while the Arduino and stepper motor rotated the chicken by 8 degrees between shots. The resulting 45 images were combined via filtered back projection to create a 3D volume reconstruction of the chicken.
Software used:
Panasonic SilkyPix (for .RW2 development)
Adobe Bridge/Photoshop for image perspective correction
Cygwin/Octave for filtered backprojection
Cone Beam Computed Tomography algorithm
3D Slicer for visualization and volume rendering
Axial image stack:
