对辐射剂量的日益关注导致CT制造商在最新一代CT扫描仪中进一步开发辐射剂量降低工具。这些工具包括自动管电流调制、自动管电位选择和迭代重建。本综述详细介绍了这3种剂量降低工具的基本原理及其在各主要供应商设备上的不同排列。如果用户设备上有，则应结合使用所有3种工具，以最大限度地节省辐射剂量。
Increasing concerns about radiation dose have led CT manufacturers to further develop radiation dose reduction tools in the latest generation of CT scanners. These tools include automated tube current modulation, automated tube potential selection, and iterative reconstruction. This review details the principles underlying each of these 3 dose reduction utilities and their different permutations on each of the major vendors' equipment. If available on the user's equipment, all 3 of these tools should be used in conjunction to enable maximum radiation dose savings.
