摘要： An imaging device includes a means for defining an imaging target space and at least two scintillation cameras which are positioned on opposite sides of the imaging target space so as to define one or more matched pairs of scintillation cameras. Each of the scintillation cameras includes a scintillation crystal. Means are provided for tilting the scintillation cameras of the one or more matched pairs of scintillation cameras and their respective scintillation crystals, so as to maximize coincidence detection sensitivity by adjusting an axial field of view to match an axial extent of a target located in the imaging target space. Means for processing signals generated by the scintillation cameras are also provided. Each pair of cameras is configured to detect paired gamma rays, emitted simultaneously and in opposite directions from a point of annihilation of a positron in the target within the target space, to thereby define endpoints of a coincidence line passing through the target and connecting the pair of cameras. Each pair of cameras generates electrical signals, responsive to substantially simultaneous absorption of each of the paired gamma rays by a respective one of the pair of cameras, indicative of the paired gamma rays emanating from a single positron annihilation in the target.
摘要翻译：成像装置包括用于限定成像目标空间的装置和位于成像目标空间的相对侧上的至少两个闪烁照相机，以便限定一个或多个匹配的闪烁照相机对。每个闪烁照相机包括闪烁晶体。提供了用于倾斜一个或多个匹配的闪烁照相机对及其各自的闪烁晶体的闪烁照相机的装置，以便通过调节轴向视场来匹配位于成像中的目标的轴向范围来最大化一致检测灵敏度目标空间。还提供了用于处理由闪烁照相机产生的信号的装置。每对相机被配置为检测从目标空间内的目标的正电子的湮灭点同时发射和相反方向发射的成对伽马射线，从而定义穿过目标并连接对的一致线的端点的相机。每对照相机产生电信号，响应于通过该对相机中的相应的一对相机基本上同时吸收每对成对的伽马射线，指示从目标中的单个正电子湮灭发出的成对伽马射线。
