Abstract(in English) | In this paper we propose a new lighter collimator than a conventional collimator for SPECT. In the new collimator we made several spaces where a septa locates in the conventional collimator. One of the, realistic form of the septa is composed of many rods whose cross section is a square or circle. Rods are aligned in x or y-axis with the interval of a hole side in a layer. We stack the layers alternatively and form a collimator These rods stop the gamma rays whose incident angle to the collimator is not exactly parallel to the hole. The weight of this collimator is less than a half of the conventional collimator with almost the same performance for stopping power. The performance of the collimator was clarified by the Monte Carlo simulation. |
