A whole body positron emission tomograph HEADTOME- IV has been developed, and its physical performances were investigated. The in-plane spatial resolution of 4.5-mm was realized with stationary-sampling at the center of the field-of-view. The axial slice thickness was 9.5 and 9.0-mm for direct and cross planes, respectively. By moving the gantry framework axially, transaxial images of 14 or 21 slices are obtained quasi-simultaneously. The real time-operation large-scale cache memory system was effective to realize (1) real time corrections for deadtime and radionuclide decay, and (2) realtime weighted integration for the purpose of a rapid calculation of rate-constant images.
