The resolution of the PET scanners is limited by the parallax error due to the missing knowledge about Depth of Interaction (DoI) of the incident photons inside the scintillation crystal. In real time, a DoI calculator must fulfill a suitable event processing rate, which requires low complexity ...
For example, when the mode is the intra mode, the general controller (621) controls the switch (626) to select the intra mode result for use by the residue calculator (623), and controls the entropy encoder (625) to select the intra prediction information and include the intra prediction ...
