Positron Emission Tomography has proved to be useful in the study of psychiatric disease such as epilepsy, neurologic disorders, brain function, cardiac metabolism, tumor detection, staging and prognosis. The PENN-PET scanner currently produced by UGM Medical Systems is designed specifically to serve the clinical needs and features a large axial field-of-view, equal resolution in all directions and a fully 3-D reconstruction method. The proposed research will lead to improved spatial resolution, improved count rate capability and more flexibility in geometry than is currently possible. The techniques to achieve this are equally applicable to single photon Anger cameras as currently used in Nuclear Medicine and these applications will also be investigated as part of the phase II work. Furthermore a new scintillator, YA1O(3)(Ce), will be investigated as an alternative to NaI(Tl).

正电子发射断层扫描已被证明是有用的研究， 精神疾病，如癫痫、神经系统疾病、脑 功能、心脏代谢、肿瘤检测、分期和预后。 UGM Medical Systems目前生产的PENN-PET扫描仪是 专为满足临床需求而设计， 轴向视场，在所有方向上的分辨率相同， 重建方法 这项研究将有助于改善 空间分辨率、改进的计数率能力和更大的灵活性 在几何形状上比目前可能的。 实现这一点的技术 同样适用于目前使用的单光子Anger相机 在核医学和这些应用也将被调查， 第二阶段的工作。 此外，还制备了一种新的闪烁体YAl O（3）（Ce）， 将作为NaI（Tl）的替代品进行研究。
