| Research Abstract |
We developed an image reconstruction algorithm for SPECT system to quantitatively image molecular functions in a selected small region with ultra high spatial resolution. In addition, for imaging with high sensitivity, we applied this algorithm to the system consisting of multiple detectors with multi-pinholes. The computer simulation showed that the combination of this high sensitive system and truncation compensated reconstruction algorithm can provide high-resolution image with high S/N ratio and no effect of truncation in a small region of human brain.
