SOLID STATE DETECTOR FOR COMPUTED TOMOGRAPHY

计算机断层扫描(CT)是一种非侵入性的医学成像技术 提供完整的人体三维图像。目前 时间CT机的性能受到所使用的X射线传感器的限制。 拟议的研究工作将调查改良镉的使用情况。 Telluride(CdTe)探测器，将在 本应用中的信噪比术语。此外，CdTe 探测器在结构上比光电二极管/闪烁体更简单 当前使用的组合。 该计划第一阶段的目标是论证 使用CdTe探测器生产性能更好的CT系统。如果 这一计划的成功将为新一代 改进的CT机器，将提供高质量的数据，减少 病人剂量。

Computed Tomography (CT) is a noninvasive medical imaging technique which provides a complete three dimensional image of the body. At the present time the performance of CT machines are limited by the X-ray sensors used. The proposed research effort will investigate the use of improved cadmium telluride (CdTe) detectors which would offer significant improvements in terms of signal to noise ratio in this application. In addition, CdTe detectors are simpler in construction than the photodiode/scintillator combinations in current use. The goal of Phase I of this program is to demonstrate the feasibility of using CdTe detectors to produce a CT system with improved performance. If successful this program would provide detectors for a new generation of improved CT machines which will provide high quality data with reduced patient dose.
