Abstract
Attenuation correction in PET using a coincidence method typically leads to 10–20 minute acquisition time per axial bed position in order to obtain adequate counts. This makes it impractical for whole body tumor surveys requiring 7–12 axial positions in a typical dedicated PET scanner. In order to reduce the acquisition time we employ a Cs-137 point source in singles mode (gamma ray energy 662 keV).
