摘要

利用高灵敏度的光谱分辨率的HPGe探测器进行了初步实验，并证明了从不同散射角度获得的两幅图像的相减得到了特定的物质分布。为了获得更精确的图像，设计了一种新的闪烁ccd探测器系统，该系统可以校正同时获得的透射CT对入射和散射光束的衰减。该系统可以在同一探测器上以高空间分辨率探测广角相干散射和透射x射线。

A coherent scatter computed tomography with scintillator-CCD system

A preliminary experiment has executed using a highly sensitive HPGe detector with spectral resolution, and it demonstrated that the subtraction of two images obtained from different scatter angles yielded a specific material distribution. To get a more exact image, a new system is designed with a scintillator-CCD detector which can correct the attenuation of incident and scattered beams by transmission CT obtained simultaneously. The proposed system can detect wide angle coherent scattered and transmitted X-rays with high spatial resolution by the same detector.
