u-CT voxel reconstruction

There are two technologies to get CT images; Fan-beam and Cone-beam. Our CT scanner is using cone-beam to take a x-ray image. The basic algorithm to reconstruct the image cross-sections is based on FDK (Feldkamp-Davis-Kress).

There are couple of open-source projects about this algorithm based on matlab.
