NEW DETECTOR CONFIGURTION FOR NUCLEAR MEDICINE

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、神经障碍、大脑 功能、心脏代谢、肿瘤检测、分期和预后。 UGM医疗系统公司目前生产的宾夕法尼亚-PET扫描仪是 专为满足临床需求而设计，并具有大型 轴向视场，所有方向分辨率相等，全三维 重建法。拟议的研究将导致改进 空间分辨率、更高的计数速率能力和更大的灵活性 在几何学上比目前可能的要好。实现这一目标的技术 同样适用于目前使用的单光子愤怒相机 在核医学中，这些应用也将作为 第二阶段工作的一部分。此外，一种新的闪烁体YAlO(3)(Ce)， 将作为NaI(Tl)的替代品进行研究。

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).
