Abstract :
The paper presents a pipeline architecture for on-line 3-D Positron Emission Tomography backprojection using an event by event algorithm that projects the single coincidence line on the three-dimensional Region of Interest. The operating mode of processors is Single Instruction stream Multiple Data stream. Real-time reconstruction requirements in terms of processing power of single processors are evaluated
