On-Line Time-Of-Flight Mashing: DMA Rebinning Applied to a Long-Axis PET-TOF System for Reduced Transaxial Angular Sampling With 3-D Nearest-Neighbor Projection-Space Rebinning in Clinical PET/CT

摘要

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.
