ABSTRACT:
A 3-dimensional projection system (10) for the rapid back projection of multi-ring Positron Emission Tomography (PET) scan data composed of planes (44) of two-dimensional data defining individual Lines Of Response (LOR) (42) into a plurality of image voxels for three-dimensional display on a video screen. The projection system (10) of the preferred embodiment is a Very Large Scale Integration (VLSI) based architecture which will support forward and back projection for a 3-dimensional image detected by a multi-ring PET scanner. A selected number of processing engines (20) are included for forward projection and back projection, the number of engines (20) being inversely proportional to the projection time.
