Abstract :
A unified Radon-transform/back-projection IC that is capable of performing the forward Radon transform and back-projection computations in a multiprocessor array architecture is being designed in a CMOS technology. The architecture of the IC and related design considerations are presented. This chip would make possible high-quality image reconstruction to 12-b resolution at video rates
