A method, developed from the Quantisation Method, of calculating dose-rate distributions around uniformly and nonuniformly loaded brachytherapy sources is described. It allows accurate and straightforward corrections for oblique filtration and self-absorption to be made. Using this method, dose-rate distributions have been calculated for sources of radium 226, gold 198, iridium 192, caesium 137 and cobalt 60, all of which show very good agreement with existing measured and calculated data. This method is now the basis of the Interstitial and Intracavitary Dosimetry (IID) program on the General Electric RT/PLAN computerised treatment planning system.
描述了一种从量化方法发展而来的，用于计算均匀和非均匀加载近距离放射治疗源周围剂量率分布的方法。它允许对倾斜过滤和自吸收进行准确而直接的校正。使用该方法，已计算出镭226、金198、铱192、铯137和钴60源的剂量率分布，所有这些结果与现有的测量和计算数据都非常吻合。该方法现在是通用电气RT/PLAN计算机化治疗计划系统中间质和腔内剂量测定（IID）程序的基础。
