| 摘 要： | CT检查以其快速、简便、无创的特点在临床应用日益广泛，如何降低CT检查的辐射剂量，尤其是降低儿童CT检查的辐射剂量是热点问题。迭代重建技术（IR）可降低儿童CT扫描剂量，联合低电压技术可进一步实现降低辐射剂量。本文对IR联合低电压技术应用于儿童低剂量CT的研究进展进行综述。

| Abstract: | CT has been widely used in clinic for its rapid, simple and non-invasive characteristics. How to reduce radiation dose, especially in children during CT has become a topical subject. Iterative reconstruction (IR) technique can reduce radiation dose of CT in children, in combination of low tube voltage can further reduce radiation dose possibly. The application of IR combined with low tube voltage technology in low dose CT in children were reviewed in this article. |
