摘要
基于对骨和软组织对不同能量X线光子吸收特性的差异的分析和对从X线源到计算机数字图象象元灰阶定量关系的讨论,提出一种从双能量X线投影照片经数学处理得到骨或软组织单一图象的算法。算法经实验证实可行。
<ABSTRACT>
Based on analysis of difference between attenuation coefficients of bone
and soft tissuos for different energy X-ray photons and discussion on
quantitafive relationship between X-ray source and pixel grey leyel of di-
gital image in computer, an algorithm is proposed for obtaining separate
bone or soft tissue images. The algorithm is proved to be feasible by ex-
periments both in phantom and human body.
