Described is an experimental verification technique for cesium brachytherapy line source emission. The dose rate levels produced by a line source algorithm are compared with measurements taken around J-series stainless-steel sheathed cesium sources with a p-type semiconductor diode detector. Further study of isodensity contours is undertaken using a film dosimetry technique. The errors involved in using these techniques are assessed.
描述了一种用于铯近距离治疗线源发射的实验验证技术。将线源算法产生的剂量率水平与使用p型半导体二极管探测器在J系列不锈钢护套铯源周围进行的测量结果进行比较。使用胶片剂量测定技术对等密度轮廓进行了进一步研究。评估了使用这些技术所涉及的误差。
