Brain PET prototypes in comparison: b and d show a brain PET constructed from conventional sizes of scintillators in single-sided readout (SiSi). In a, c and e are different views of the double-sided readout (DoSi) model. The detector ring is not shown in its entirety for illustrative purposes. The scintillation crystals are shown in grey, the SiPMs in green. The white line is the best possible resolution of the LOR and in red the error on the LOR determination due to parallax error. The human model used is based on [14]. a The detector ring is positioned around the head of a seated patient, b top view of a classical readout detector type, c top view of the novel readout detector type, d side view of a classical readout detector type, e side view of the novel readout detector type
