摘要
与传统的滤过反投影法相比,迭代重建技术可在低SNR的条件下获得噪声较少的高质量CT图像,大幅降低CT扫描的辐射剂量。本文对迭代重建的技术原理及其在低剂量CT扫描中的临床应用进展进行综述。
Compared with conventional filtered back projection method,using iterative reconstruction（IR） can obtain high quality CT images with low noise under low SNR conditions.It can also greatly reduce radiation dose of CT scan.The technique principle and clinical application progress of IR in low dose CT scan were reviewed in this article.
