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 realtime-operation large-scale cache memory system was effective to realize realtime corrections for deadtime and radionuclide decay, and realtime weighted integration for the purpose of a rapid calculation of rate-constant images.
