Hi all, looking for a recon code to reconstruct projections from a CT scanner , for a CURVED detector, the one I am using (3D Cone beam CT,Matlab file exchange)is for flat detector and I dont know how to change it for curved detector

Thanks Hany

Shouldn't that just be a minor geometric transformation between the angles to your detector and the angles to the flat detector of the CT-toolbox, and possibly a simple scaling due to the difference in distance between your curved and the toolbox flat detectors. You should be able to work that out fairly easy with pen and paper. Note that I've never worked with that toolbox...
