A parallel architecture for Digital Radiography

Off-line reconstruction of digital radiographic images obtained with a double side silicon micostrip detector requires a huge amount of computing resources. We suggest the use of a distributed-memory parallel architecture to increase the speed of a possible ‘in list’ system for Digital Radiography. We present a mathematical model of the expected performances of a pipeline parallel architecture. Results of experiments made with software synthetized images on a Transputer-based system with up to eight nodes show the effectiveness of our approach.
