โœฆ Synopsis

Long reconstruction times in three-dimensional (3D) positron emission tomography (PET) have long remained an obstacle to its routine clinical use. This article presents an experimental study of various algorithms on a compact parallel platform consisting of five hybrid nodes, each equipped with a Transputer TM and an Alpha processor. Resulting execution times for the data set of a 16-ring PET tomograph (256 sinograms of 96 views by 128 radial samples) lie under 2 min, thus eliminating the time factor in practice and making 3D PET more generally accessible.
