<p>This invention addresses the practical implementation of PET imaging capability on a conventional gamma camera. The primary subject of this invention is the addition of a real time processor to perform the rebinning calculations and other on-the-fly calculations and procedures to make PET imaging on a gamma camera more practical. The rebinning or transformation operation described above is performed on-the-fly as each event pair is detected with an event throughput rate sufficient for clinical applications. This transformation process is performed by a chain of digital signal processing subsystems (or similar real time processors), with the resultant transformed data stored in a memory subsystem until a sufficient number of events have been received to produce an image of acceptable quality.</p> |
