PARALLEL-BEAM TOMOGRAPHIC IMAGE RECONSTRUCTION This projects reproduces results of procedures regarding CT Image Reconstruction. The application will applied to computed tomography single photon emission (SPECT) data . In particular, the following

This example shows how to scan an image with a limited angle, obtain the sinogram, add noise to make things worse, and reconstruct the initial image with great accuracy %You may want to remove/edit some sections if you intend to apply this to your u
