Most of the objects targeted for X-ray examination are composed of soft-tissue and bone. We aimed to develop an algorithm for generating X-ray images which can give quantitative information of soft-tissue and bone using an energy-resolving photon-counting type imaging detector. We used polychromatic X-rays for analysis in which both the beam hardening effect and detector response were properly corrected and then succeeded in virtually treating the amount of measured X-ray attenuation as if it were measured using monochromatic X-rays.
大多数接受 X 射线检查的物体都是由软组织和骨骼构成的。我们的目标是开发一种算法,利用能量分辨光子计数型成像探测器生成可提供软组织和骨骼定量信息的 X 射线图像。我们使用多色 X 射线进行分析,对束硬化效应和探测器响应进行适当校正,然后成功地将测量的 X 射线衰减量视为使用单色 X 射线进行测量。
