A transputer system was used for fast 3-D image reconstruction in 3-D PET (positron emission tomography). The optimization of the algorithm (written in Occam language) and its parallelization on the transputer system for its use in the HISPET (high spatial resolution PET) project are discussed. It is projected that a 100-transputer machine would suffice in processing process online data at approximately=10 kHz for a matrix volume of 128*128*128 voxels, i.e. at a rate which is one-tenth of the maximum acquisition rate for the HISPET project.< >
