三维适形放疗技术的临床应用是肿瘤放射治疗发展的一个里程碑,利用三维适形放疗技术可增加肿瘤剂量,减少正常组织受量,在达到提高肿瘤治愈率和控制率的同时,减少了放疗不良反应,但是在实施放疗过程中的精确度则是一个非常重要的问题。如何利用现有设备来达到精确放疗是值得研究
The clinical application of three-dimensional conformal radiotherapy is a milestone in the development of radiation therapy for cancer. The use of three-dimensional conformal radiotherapy can increase the dose of tumor and reduce the amount of normal tissue. With the improvement of tumor cure rate and control rate, it can reduce the adverse radiotherapy Response, but the accuracy of the implementation of radiotherapy is a very important issue. How to use the existing equipment to achieve accurate radiotherapy is worth studying
