Abstract Iterative model reconstruction (IMR) technology is a new type of iterative reconstruction algorithm. Compared with the traditional filtered back projection and hybrid iterative algorithm, it performs better in reducing noise and improving image quality. Application of IMR reconstruction can reduce the radiation dose and ensure the image quality. In this paper, the clinical application progress of IMR technology in CT angiography of various parts is reviewed, and a simple estimation is made to provide reference for related research.
