放射疗法是治疗肿瘤的一个重要手段,剂量的确定以及放射线的分布是关系到对肿瘤的作用效果和对周围器官的影响如何的一个重要问题。过去用一般的计算方法计算出一个完整的放射治疗计划需要3～5天的时间。为了多快好省地解放治疗计划的制订,上海肿瘤医院和上海计算机技术研究所、上海医疗器械研究所等单位协作,于一九七七年成功地应用电子计算机运算并描绘出~(60)钴 Radiation therapy is an important means to treat tumors. The determination of the dose and the distribution of radiation are an important issue related to the effect on the tumor and how it affects the surrounding organs. In the past, using a general calculation method to calculate a complete radiation therapy plan took 3 to 5 days. In order to quickly establish a plan for the liberation of the province, Shanghai Cancer Hospital cooperated with the Shanghai Institute of Computer Technology and the Shanghai Institute of Medical Devices. In 1977, it successfully applied computer computing and described ~(60) cobalt
