摘要
目的:通过对使用一楔合成技术的肿瘤处方剂量的计算,使得临床治疗中肿瘤得到准确的剂量,使靶区内的剂量分布更加均匀,适形度更好,重要器官得到保护,正常组织尽可能少的受到照射。材料与方法:1、用水箱测得60°主楔形因子。2、通过一楔合成平野和楔形野的比率及公式计算临床处方剂量。结果:通过实测得到60°主楔形因子后,举例说明使用一楔合成后处方剂量计算的结果。结论:对使用一楔合成技术的肿瘤剂量进行严格的,准确的计算,对放射治疗的治疗控制和保证提供保证。
Objective Through the use of autowedge, the clinical treatment and accurate dose is more exactitude and the dose distri- bution more uniform. The vital organs are protected, normal tissue as little as possible by irradiation. Material and Methods： 1. Measure the 60 degrees wedge factor by water tank 2. Calculated the clinical prescription dose through the formula and the ratio of open and wedged. Results： Apart from the article on the elaboration, in relevant chapters the author are detailed enumerates some examples are calculated. Conclusion： The tumor dose which using autowedge is Accurate calculated. And this is very importance on QA and QC.
