Abstract

We have designed the concept of practical high spatial-resolution SPECT for human brain. This study suggested combination PSPMTs with full-digital circuit can achieve detector intrinsic spatial resolution less than 2 mm. Image reconstruction software will compensate decrease of sensitivity due to collimator for high resolution. This system is expected to have the system resolution of 3-4 mm and the sensitivity higher than that in conventional clinical SPECT system.
