摘要:
三维适形放疗是治疗肿瘤的一种主要的外照射治疗方式,如:前列腺癌、头颈部癌、乳腺癌和肺癌等。与传统的放疗相比,它能提高肿瘤靶区剂量,减小旁邻正常组织的剂量,降低辐射引起的急性和远期效应。调强放疗则是在常规适形放疗技术的基础上,对射束内束流强度的空间分布进行调制,得到更好的治疗效果。
Abstract:
Three-dimensional conformal radiotherapy is a mostly-used external radiotherapy for some tumors, e.g. prostate carcinoma, head and neck cancer, breast cancer and lung cancer ect. Compared with the conventional radiotherapy, it can improve the dose to the target area in the tumor and reduce the ones to the proximal normal tissues and in return, decreases the probabilities of irradiation induced acute and long-term effects. Developed on the technology basis of conventional conformal radiotherapy, intensity modulated radiotherapy (IMRT) modulates the intensity spatial distribution in the incident beam, obtaining much better therapeutic effect.
