Hi, There is no FBP implementation for spiral CT. The only way this could work is with iterative algorithms (e.g., conjugate gradient) using Joseph forward and backprojectors. Voxel-based backprojector (the default) won't work because it does a bilinear interpolation on the projections. I don't have an example available for you, sorry... Cheers, Simon
