摘要
质子放射治疗近年来有了较快的发展,世界上作为研究用的很多家质子治疗机构早就在运行,作为商业产品的质子放疗机也已经有多台设备在世界各地安装和运行.质子束对于肿瘤治疗比其它放疗模式优越的地方主要在于利用质子束的Bragg峰,更好地适形包络肿瘤的不同形状,其包络的边界比X和γ-射线更锐.质子放疗之所以能够商业化,得益于质子加速器技术和质子剂量学的进步,以及包括核心部件在内的整套设备的可靠性大大提高.但是质子放疗在运动靶区和实时的影像监督方面也还有很多问题仍然需要进一步完善.以山东淄博万杰医院为代表,国内也已经开始质子放疗的临床工作,还有医院正在筹建.作为处于商业化初级阶段的质子放疗,由于设备的复杂性和价格,在中国还缺乏合格的医学物理师和维护工程师的情况下,这类放疗设备不宜大量发展.
Prolon lherapy has a rather quick progress going with lhe developmenl of proton acceleralor and proton dosimeter, as well as the stability and the reliability of proton therapy facility. Many proton therapy centers were installed and slarl to run recent years. Proton therapy has its own advantages in the treatment of cancer. Taking the advantage of Bragg Peak, proton therapy has a belier coverage to the target and sharper penumbra than X-Rays. Also there are some potential problems such as how to match the moving target with the inspection of radiograph, Some proton therapy centers have been buih or under construction now in China and some clinical cases have been done in Wanjie Hospital, At its beginning of commercialization, proton therapy should not be possible to grow up as fast as X- ray therapy for its complexities, expensiveness. As well as for it is a special problem in China, there are not so many qualified medical physicists and maintenance engineers at present.
