放射线位置检测方法、放射线位置检测器及PET装置
摘要：
本发明涉及放射线位置检测方法、放射线位置检测器及PET装置。放射线位置检测方法包括：第一步骤，基于电信号，对于检测出闪烁光的位置计算出入射方向上的第一重心位置；第二步骤，基于显示了用于识别多个段的第一识别区域的第一表及第一重心位置，特定最初产生闪烁光的段。第一识别区域具有第一区域、第二区域和第三区域。在第二步骤中，在第一重心位置位于第一区域或第三区域时，将第一段特定为最初产生闪烁光的段，在第一重心位置位于第二区域时，将第二段特定为最初产生闪烁光的段。
摘要（英）：

The disclosure relates to a radiation position detection method, a radiation position detector, and a PET apparatus. The radiation position detection method includes: a first step of calculating a first centroid position in an incident direction regarding positions where scintillation light is detected, on the basis of electrical signals; and a second step of specifying, on the basis of a first table showing first identification regions for identifying the plurality of segments, and the first centroid position, the segment that initially generates the scintillation light. The first identification region includes a first region, a second region, and a third region. In the second step, in a case where the first centroid position is located in the first region or the third region, the first segment is specified as the segment that initially generates the scintillation light, and in a case where the first centroid position is located in the second region, the second segment is specified asthe segment that initially generates the scintillation light.
