EVALUATION OF A FULLY 3-D BPF METHOD FOR SMALL ANIMAL PET IMAGES ON MIMD ARCHITECTURES
1999
International Journal of Modern Physics C
Positron Emission Tomography (PET) images can be reconstructed using Fourier transform methods. This paper describes the performance of a fully 3-D Backprojection-Then-Filter (BPF) algorithm on the Cray T3E machine and on a cluster of workstations. PET reconstruction of small animals is a class of problems characterized by poor counting statistics. The low-count nature of these studies necessitates 3-D reconstruction in order to improve the sensitivity of the PET system: by including axially
