Research has been done on optically reconstructed imaging employing the Multiple Pinhole Coded Aperture (hereafter abreviated as MPCA) in radioisotope tomographic imaging. However, problems remain in the optically reconstructed image method. Therefore, we employed a minicomputer (hereafter abbreviated as CPU) and developed the software for decoding and managing the radioisotope tomographic image. Combining the MPCA and the CPU system, we were able to decode and manage the radioisotope tomographic image. 1) In comparison to the optically decoded MPCA image, various input commands are possibly in the CPU method according to the dialogue between the CPU and the on line typewriter. In addition to this, decoded tomographic images of unrestricted depth are readily attainable. 2) In the CPU method noise elimination and other aspects of image management can be easily performed.
已经开展了关于在放射性同位素断层成像中采用多针孔编码孔径（以下简称为MPCA）进行光学重建成像的研究。然而，光学重建图像方法仍存在问题。因此，我们使用了一台小型计算机（以下简称为CPU）并开发了用于解码和管理放射性同位素断层图像的软件。将MPCA和CPU系统相结合，我们能够对放射性同位素断层图像进行解码和管理。1）与光学解码的MPCA图像相比，根据CPU与在线打字机之间的对话，CPU方法中可能有各种输入命令。除此之外，还能轻松获得不限深度的解码断层图像。2）在CPU方法中，可以轻松进行噪声消除和图像管理的其他方面。
