医用辐射新技术应用中的辐射防护问题

目前的医用辐射防护研究已远远超出了单纯的职业人员和病人的防护范畴,而是与新的放射治疗技术融合在一起.由此不但深化了辐射防护研究,而且成为推动新治疗技术发展的重要动力.新的医用辐射诊断和治疗技术一出现,人们关心的是这些技术的应用和推广,而往往忽视这些辐射技术在医学中应用的正当性判断和防护最优化问题,从而带来了一些严重的问题,也就成了目前医用辐射防护中值得关注的新问题.本文重点讨论在导向治疗、腔内近距放射治疗和立体定位放射治疗等新技术中的有关辐射防护问题.

Concerns over Radiation Protection Problems Emerging in Application of Medical Radiological Technology

For the being time, the study on medical radiation protection is not only focused on the protection of occupational workers and patients but also on the accompanied new radiotherapy technology. While enhancing medical radiation protection, this situation leads to a strong promotion of new radiotherapy technology. With the appearance of a new technology for diagnosis and therapy, concerns are directed to their application and promotion while ignoring the optimization and justification in medical application. Thus, concerns over such problems arise in medical radiation protection. This paper would place focus .on the problems associated with new radiotherapy technology, like oriented therapy, intracavitary brachythempy, stereotactic radiotherapy.
