Abstract :
An expandable multiprocessor hardware system for the computation of the Radon transform and backprojection equations is described. The system is constructed with commercially available digital signal processing (DSP) chips. This Radon transform processor is based upon a parallel-pipelined multiprocessor architecture. Performance characteristics of the hardware system are presented
