The potential risks of radiation exposure associated with computed tomography (CT) imaging are reason for ongoing concern for both medical staff and patients. Radiation dose reduction is, according to the as low as reasonably achievable principle, an important issue in clinical routine, research and development. The complex interaction of preparation, examination and post-processing provides a high potential for optimization on the one hand but on the other a high risk for errors. The radiologist is responsible for the quality of the CT examination which requires specialized and up-to-date knowledge. Most of the techniques for radiation dose reduction are independent of the system and manufacturer. The basic principle should be radiation dose optimization without loss of diagnostic image quality rather than just reduction.
计算机断层扫描（CT）成像所带来的辐射暴露潜在风险，一直是医护人员和患者持续关注的问题。根据合理可行尽量低原则，降低辐射剂量是临床常规、研发中的一个重要问题。准备、检查和后处理之间的复杂相互作用一方面提供了很大的优化潜力，但另一方面也存在很高的出错风险。放射科医生负责CT检查的质量，这需要专业的最新知识。大多数降低辐射剂量的技术与系统和制造商无关。基本原则应该是在不损失诊断图像质量的前提下优化辐射剂量，而不仅仅是降低剂量。
