Abstract

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
