A positron camera system PC-384 has been designed and built for quantitative positron emission computed tomography of the brain. This head scanner consists of 384 bismuth germanate oxide scintillation detectors with a crystal packing fraction of 80%. The entire detector assembly rotates around a small circle (wobble) to achieve the necessary ray sampling. Seven simultaneous images are produced with four detector rings. Performances of the system are discussed and clarified based on experimental data.
已设计并制造了一台用于脑部定量正电子发射计算机断层扫描的正电子相机系统PC - 384。这台头部扫描仪由384个锗酸铋闪烁探测器组成，晶体填充率为80%。整个探测器组件围绕一个小圆圈（摆动）旋转，以实现必要的射线采样。四个探测器环可同时生成七幅图像。基于实验数据对该系统的性能进行了讨论和阐明。
