Research Abstract

To develop a new SPECT system with a static data acquisition using semiconductor detectors, a data acquisition method and image reconstruction method were developed with a simulation study. The validity of these methods was confirmed with a newly developed myocardial SPECT system and brain SPECT system with CdZnTe semiconductor detectors.
