摘要：
The purpose of our research is to develop a new multi pinhole SPECT system using a triple head gamma camera system. The proposed data acquisition geometry used a multi-pinhole collimator attached to each gamma camera. We made a multi pinhole SPECT system with a commercially available gamma camera (GCA-9300R). Eight pinholes were evaluated in this study and the diameter of a pinhole was 5 mm. A squired data were reconstructed with the OS-EM method. In the experiment we used a three hot-rod phantom and myocardial phantom. As the reference we acquired projection data with the parallel hole collimator. The results of the experiment demonstrated the feasibility of our proposed multi-pinhole SPECT system with a triple head gamma camera.
