PET Detector

描述（由申请人提供）：LightSpin Technologies, Inc.提议开发一种用于PET和SPECT应用的创新固态微通道光电探测器（SSMCP）。这是第一个室温固态光电探测器，性能优于光电倍增管。SSMCP是单光子敏感的，但也实现了宽动态范围和高线性。SSMCP提供高增益（105 - 106），低多余噪声因子（ENF < 1.1），超快上升时间（< 100 psec），超快定时分辨率（<50 psec），工作电压低（< 100 V），结构紧凑且坚固。在SBIR项目的第一阶段，SSMCP的组件技术被成功地设计、制造、建造和测试，证实了我们的方法。在第二阶段，将展示大面积SSMCP，具有8 mm x 8 mm的光敏区域，量子效率高于20%，黑暗计数率低于1 Mcps。这些大面积ssmcp有望通过提供更高的灵敏度、更高的时序分辨率、改进的动态范围和优越的位置灵敏度来提高PET探测器的性能。

DESCRIPTION (provided by applicant): LightSpin Technologies, Inc., proposes to develop an innovative, solid-state microchannel photodetector (SSMCP) for PET and SPECT applications. This is the first room temperature solid-state photodetector capable of outperforming photomultiplier tubes. The SSMCP is single photons sensitive, but also achieves a wide dynamic range and high linearity. The SSMCP provides high gain (105 - 106), low excess noise factor (ENF < 1.1), ultrafast rise times (< 100 psec), ultrafast timing resolution (<50 psec), operates at low voltage (< 100 V), is compact and robust. In Phase I of this SBIR project, component technologies for the SSMCP were successfully designed, fabricated, and built, and tested, confirming our approach. In Phase II, a large area SSMCP will be demonstrated, with an 8 mm x 8 mm photosensitive area, quantum efficiencies above 20% and dark count rates below 1 Mcps. These large area SSMCPs are expected to improve the performance of PET detectors by providing higher sensitivity, higher timing resolution, improved dynamic range, and superior position sensitivity.
