In PET-CT the axial length of image reconstruction is defined by the CT scan, which delivers an axial extend-dependent radiation dose. The beginning and end scanning points for CT and therefore PET scans are typically chosen in such a way that the PET scan is performed with a particular number of beds. While PET bed overlapping is optimized to achieve uniform image sensitivity, the whole volume edge planes suffer from low sensitivity, since only direct plane LORs are available from the… CONTINUE READING
