In a SPECT system with CdTe semiconductor detectors, it is difficult to achieve a wide effective filed-of-view (FOV) due to the manufacturing process and the cost. We therefore proposed a diverging SPECT system which used a diverging collimator and a CdTe detector with a small active area. However, this introduced a problem of a shadow zone in Radon space. To cope with the problem, we introduced the algorithm proposed by Yang et al. into the diverging SPECT system and reconstructed high quality images. |
