PET Detector

描述(由申请人提供)：LightSpin Technologies，Inc.计划开发一种用于PET和SPECT应用的创新固态微通道光电探测器(SSMCP)。这是第一个能够超越光电倍增管的室温固态光电探测器。SSMCP是单光子敏感的，但也实现了宽动态范围和高线性度。SSMCP具有高增益(105-106)、低过剩噪声系数(EnF&lt；1.1)、超快上升时间(&lt；100PSEC)、超快定时分辨率(&lt；50PSEC)、低电压(&lt；100V)、紧凑和坚固耐用的特点。在SBIR项目的第一阶段，SSMCP的组件技术成功地设计、制造、制造和测试，证实了我们的方法。在第二阶段，将展示一种大面积SSMCP，其感光面积为8 mm×8 mm，量子效率高于20%，暗计数率低于1 MCPS。这些大面积的SSMCP有望通过提供更高的灵敏度、更高的时间分辨率、更好的动态范围和更好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.
