摘　　要：如何在不影响图像质量的前提下降低CT对患者的辐射剂量是近年来医学影像学研究的重点。本文对近年来主流的CT机低剂量技术如迭代算法、自动管电流调节技术、双源CT技术的原理及应用进行了简介,并着重介绍了这些CT低剂量技术在肺部、心脏冠脉、腹部、头颅中的临床研究及应用,提出了对该技术未来发展方向的看法。Decreasing CT radiation dose without affecting image quality is an important direction for research of medical imaging in recent years. This paper introduced the principle and application of mainstream CT low dose technologies in recent years, such as iterative algorithm, automatic tube current adjusting technology, dual source CT technology, and emphatically detailed the clinical research and application of low dose CT technology in lung, heart coronary artery, abdomen and head. It also put forward views of the future development direction of the technology.
