As an illustration of some techniques from my series of articles on tomography, I have added a tool that demonstrates basic scanning and reconstruction. Go to the tool. There are several phantoms to choose from, and the tool allows you to change the number of projections and to introduce a variable missing wedge of projections. Reconstruction is, for the time being, limited to classical filtered backprojection (FBP) and unfiltered backprojection.
