DIY X-ray CT scanner controlled by an Arduino (2013x1)

Data de estreia: Jan 08, 2013

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 http://www.mathworks.com/matlabcentral/fileexchange/35548-3d-cone-beam-ct-cbct-projection-backprojection-fdk-mlem-reconstruction-codes-for-matlab-students 3D Slicer for visualization and volume rendering http://www.slicer.org/ Axial image stack: https://drive.google.com/file/d/0B4YXWiqYWB99Z3pTRUE5WDZrdVU/
