Not even a week passes without a paper getting published in peer reviewed journals on radiation protection in newer imaging technologies that either did not exist 10 y ago or were not established for routine use. Computed tomography (CT) happens to be a common element in most of these technologies. Radiation protection is high on the agenda of manufacturers and researchers and that is becoming a driving force for users and international organisations. The media and thus the public have their own share in increasing the momentum. The slice war seems to be shifting to dose war. Manufacturers are now chasing the target of sub-mSv CT. The era of two digit mSv effective dose for a CT procedure is far from losing ground, although cardiac CT within 5 mSv seems possible. A few years ago the change in technology was faster than adoption of dose management but currently even the development of dose reduction techniques is faster than its adoption. There is dearth of large-scale surveys of practice and lack of surveys with change in technology.
甚至不到一周，就会有一篇关于新型成像技术中辐射防护的论文在同行评审期刊上发表，这些技术要么在10年前不存在，要么尚未确立用于常规使用。计算机断层扫描（CT）恰好是大多数这些技术中的一个常见元素。辐射防护在制造商和研究人员的议程上占据重要位置，并且正成为推动用户和国际组织的一股力量。媒体以及公众也在推动这一势头的增强。切片大战似乎正在转向剂量大战。制造商们现在正在追逐亚毫希沃特CT的目标。CT检查程序有效剂量达到两位数毫希沃特的时代远未失势，尽管心脏CT检查在5毫希沃特以内似乎是可能的。几年前，技术变革的速度比剂量管理的采用速度更快，但目前即使是剂量降低技术的发展速度也比其采用速度更快。缺乏大规模的实践调查，也缺乏随着技术变化而进行的调查。
