等剂量 meaning in English

isodose

In this thesis , ga is used to optimize the beam weights of intensity modulated radiation therapy ( imrt ) inverse planning , and 2d and 3d isodose contour as well as dose volume histogram ( dvh ) are used to evaluate the treatment plan
本文应用遗传算法优化逆向调强放疗计划中射束的权重，用二维等剂量线、三维剂量分布和剂量体积直方图来评估计划的优劣。
The doctors can observe the relationship and geometry of the organs and the tumors , from the 3d model of the human body , which can help them create the therapy plan . the radiation dosimetry is built using monte carlo method . after we extract the iso - surfaces from the volume of the doses , the relationship between radiation doses and the cancer is represented on a 3d model , which is greatly helpful for the doctors to improve their therapy plan
通过建立三维人体模型，可以帮助医生直观的观察人体内部病灶及组织器官的形态位置尺寸，并获得其量化指标，从而更加准确的制定治疗计划：根据初步的放疗计划，使用montecarlo方法建立模拟的放射剂量分布数据场，再通过等值面提取方法获得等剂量面，显示并量化剂量分布情况和病灶(靶区)的关系；根据模拟的结果对放疗计划进行适当修改，并最终获得最佳的放射治疗计划。
