Abstract
A system for generating time-of-flight (TOF) positron emission tomography (PET) projection data includes a direct memory access rebinner constructed as a digital FPGA pipeline for rebinning TOF coincidence data in accordance with a number of projection space mapping algorithms, such as single-slice rebinning (SSRB) and reduced multiple-slice rebinning (MSRB), together with less precise transaxial and/or axial sampling.
