Abstract

A method for 3D cone beam tomographic reconstruction from limited data has been developed. This method uses a modified form of convolution backprojection and projection onto convex sets for handling the limited data problem. Convex constraints applicable to cone beam projection data have been identified, and their associated projection operators have been used. The algorithm has been tested with simulated data for circular source point trajectory. The method however is independent of source point geometry, and will be useful in any limited view cone beam reconstruction.
