Locoregional control and the relationship between the site of residual or recurrence and target volumes in radiography were analyzed after treatment.
分析治疗后局部区域控制情况以及影像学显示的残留和复发部位与靶体积的关系。
For a target volume larger than one shot, multiple shots can be used to cover the entire target. In practice, most target volumes are treated with 1 to 15 shots.
如果治疗的区域大于一个单位的治疗区域,就需要用多次照射来覆盖整个治疗区域,在实践中,大多数的目标体积被照射1至15次。
Imaging is used to precisely define target volumes, to qualify and quantify geometric uncertainties and errors, and to correct and compensate for uncertainties and errors.
成像技术可用来精确定位靶区,限制并量化几何不确定因素及误差,校正并补偿几何不确定因素及误差。
