剂量测定工作是肿瘤放射治疗的基础,剂量是否准确关系到肿瘤治疗的成败,也关系到肿瘤放射治疗后在各放射治疗单位间疗效能否对比的关键。为此,我室对60钴治疗的剂量进行了一系列测定,现小结于后,以供同志们参考,并希望提出宝贵的意见。(一)照射野的大小与输出量的关系。~(60)钴治疗机的输出量与源一皮肤距离,射野大小,准直系统(遮线器)的 Dosimetry is the basis of tumor radiotherapy. The accuracy of the dose is related to the success or failure of tumor treatment. It is also related to whether the efficacy of tumor radiotherapy after treatment in each radiation therapy unit can be compared. To this end, our lab conducted a series of measurements on the dose of 60 Cobalt, which are now summarized for reference by comrades and hope to provide valuable suggestions. (A) The relationship between the size of the field and the output. ~ (60) Cobalt Healing Machine Output and Source-to-Skin Distance, Shot Size, Collimator System (Clipper)
