Techniques by which the quantitative anatomical data inherent in a CT scan can be directly used in treatment planning are described. The correction algorithms used in the RAD-8 system, based on an effective path length, have been extended to a pixel-by-pixel approach. By calibrating the X-ray transmission CT scanner in terms of electron densities (electron cm-3) inhomogeneity corrections may be made automatically.
本文描述了能将CT扫描中固有的定量解剖数据直接用于治疗计划的技术。基于有效路径长度的RAD-8系统中使用的校正算法已扩展为逐像素方法。通过根据电子密度（电子每立方厘米）对X射线透射CT扫描仪进行校准，可以自动进行不均匀性校正。
