Abstract :
An architecture for the real time parallel processing of data coming from a 3D PET is shown. Also if the adopted reconstruction algorithm is a well-known one, the originality of the paper consists of a suitable data management policy employed in order to allow a real-time parallel processing. Because of both the short time required for an I/O operation (at present 150 ns) and of the simplicity of the computations (parallel additions requiring computing time of the order of the address-encoding), the shown architecture can be added (by the interposition of a FIFO buffer) to an existing tomograph in order to obtain the real time 3D PET data processing and the image reconstruction
