放射治疗历经十几年的发展和技术革命,相继研发了三维适形放疗技术、调强放疗技术和质子放疗技术等,这些技术的进步体现在对靶区剂量分布的适应性有了一定的提高。人类在同肿瘤疾病进行斗争的过程中,不断深入了解了对疾病的认识,治疗手段也在不断完善,肿瘤放射治疗在临床中取得了很好的效果,受到人们的信任和青睐。但是,对肿瘤放射治疗的认识和机理还需要加深认识和了解。阐述了肿瘤放射治疗的相关基本知识,介绍了现有的放射治疗技术,并指出存在的问题,对未来肿瘤放射治疗技术的发展做一展望。 Radiation therapy after more than ten years of development and technological revolution, have developed three-dimensional conformal radiotherapy technology, intensity modulated radiotherapy and proton radiotherapy techniques, these advances are reflected in the target dose distribution flexibility has been improved . In the process of struggling with cancer diseases, human beings are constantly aware of their understanding of the disease and their treatments are constantly being improved. Tumor radiotherapy has achieved good results in clinical practice and is trusted and favored by people. However, the understanding and mechanism of tumor radiotherapy need to deepen our understanding and understanding. The basic knowledge about tumor radiotherapy is expounded, the existing radiotherapy techniques are introduced, the existing problems are pointed out, and the prospect of future radiotherapy techniques is prospected.
