为了评估多环照相机用于三维PET（正电子发射断层扫描）的潜力，从商业生产的PET照相机（ECAT 931/08-12）中取出隔片。对数据采集子系统进行了近似重新配置，以采集包含探测器对之间所有允许响应线的全套64张正弦图。用这种相机配置对许多不同的体模成像，并对健康志愿者进行了一项氟多巴研究。作者讨论了这些研究的结果，并描述了反投影和过滤程序，已被采用，以将最大量的跨平面数据的重建。将结果与使用标准二维方法重建的相同数据（即仅针对直接平面和交叉平面）进行比较，并与针对具有隔膜的相同体模收集的数据进行比较。>
In order to assess the potential of a multiring camera for three-dimensional PET (positron emission tomography) the septa were removed from a commercially produced PET camera (ECAT 931/08-12). An approximate reconfiguration was made to the data acquisition subsystem to acquire the full set of 64 sinograms containing all permitted lines of response between pairs of detectors. A number of different phantoms were imaged with this camera configuration, and one fluorodopa study was performed with a healthy volunteer. The authors discuss the results of these studies, and describe the back-projection and filtering procedure that has been adopted in order to incorporate the maximum amount of cross-plane data in the reconstruction. The results are compared with the same data reconstructed using the standard two-dimensional approach (i.e. for the direct and cross planes only), and with data collected for the same phantoms with the septa in place. >
