Abstract
A tomography processor system for processing data from a plurality of projections in essentially real time to produce a reconstructed image immediately following completion of a scan. The system includes specialized high-speed processing stages for performing required calculations and operating in concert with a low-cost computer providing overall system control. These processing stages form a multi-stage pipeline processor capable of performing the correction, convolution, interpolation, and back projection functions required to reconstruct the desired final image. The invention makes use of a reconstruction algorithm particularly adapted to implementation in the manner disclosed and claimed.
