IMPROVING RESOLUTION IN WRIST SPECT WITH CONVERGING COLLIMATORS AND CT ANATOMICAL PRIORS
… wrist SPECT resolution can be improved by using pinhole collimators and by incorporating anatomical prior information. Phantom experiments have shown that a 3mm single-pinhole system can achieve a 4mm resolution at clinical count levels, but a 3mm resolution required 4-times as many counts. …
