调强放射治疗应用于早期鼻咽癌,在提高肿瘤控制的同时,降低了正常组织并发症,提高了患者的生活质量。随着电子计算机X线体层显像、磁共振成像、正电子发射计算机体层扫描技术融合的应用以及对靶区勾画、照射野设置、调强给量方式等认识的加深,调强放射治疗有了进一步的发展。但在调强放射治疗的靶区勾画、放射物理、放射生物学方面还存在许多问题,值得进一步研究。
IMRT applied to early nasopharyngeal carcinoma, in improving tumor control at the same time, reducing the complications of normal tissues and improve the quality of life of patients. With the computer tomography, magnetic resonance imaging, the integration of positron emission tomography and its application in the field of computer tomography, the understanding of target setting, setting of radiation field, and the method of adjusting the intensity of the light intensity, With further development. However, there are still many problems in the target mapping, radiophysiology and radiobiology of intensity modulated radiation therapy and it deserves further study.
