One can achieve a high precision in the dosing of a session of intracavitary radiotherapy by rapid computerization of the treatment time that is necessary for obtaining a certain dose in a pathological focus taking account of an actual location of radiation sources in the process of irradiation. The authors have developed an algorithm and drawn up a program for computer ES-1022 to calculate a dose rate in any point of an irradiated volume from the system of gamma-radiation sources oriented arbitrarily in space. As part of a hard- and soft ware dosimetric complex, the above program provides for the calculation of the treatment time by a set dose; the time is necessary for supplying this dose to a tumor focus taking account of an actual location of radiation sources during a session of irradiation. The whole computer procedure from the moment of obtaining necessary anatomo-topographic information in the form of two x-ray pictures up to the output of an irradiation session time value and other information into the alpha-numeric printer takes 3-5 min. The program makes it possible to calculate dose distribution in any preset plane (up to 4 planes at a time) of an irradiated volume.
通过快速计算机化治疗时间，考虑到照射过程中辐射源的实际位置，在病理病灶中获得一定剂量所需的时间，就可以在腔内放射治疗的一次疗程中实现高精度的剂量控制。作者开发了一种算法，并为计算机ES - 1022编写了一个程序，用于计算来自在空间中任意定向的伽马辐射源系统的照射体积中任意点的剂量率。作为硬件和软件剂量学复合体的一部分，上述程序根据设定剂量计算治疗时间；在照射疗程中考虑辐射源的实际位置，将该剂量提供给肿瘤病灶所需的时间。从以两张x光片的形式获得必要的解剖地形信息的那一刻起，到将照射疗程时间值和其他信息输出到字母数字打印机的整个计算机程序需要3 - 5分钟。该程序能够计算照射体积中任何预设平面（一次最多4个平面）的剂量分布。
