目的研究乳腺癌术后辅助放射治疗的定位、摆位方法及注意事项,使放射治疗达到预期的目的。方法分析68例乳腺癌手术后辅助放射治疗过程的注意事项及照射技术。结果使用模拟定位机、直线加速器(双光子、多档电子线)、乳腺治疗定位托架等设备顺利完成辅助性放射治疗。结论放射治疗作为保乳术及乳腺癌改良根治术后的辅助治疗,照射技术尽可能简便易行,便于技术员操作,重复性好。
Objective To study the location, setting method and precautions of postoperative adjuvant radiotherapy for breast cancer so as to achieve the expected goal of radiation therapy. Methods 68 cases of breast cancer after adjuvant radiotherapy process considerations and irradiation techniques. The results of the use of simulated positioning machine, linear accelerator (two-photon, multi-file electronic line), breast positioning brackets and other equipment to complete the auxiliary radiotherapy. Conclusion Radiation therapy is an adjuvant therapy after conservative radical mastectomy and modified radical mastectomy. The irradiation technique is as simple and convenient as possible for technicians to operate with good repeatability.
