Abstract

The present invention provides a CT image reconstruction method, the method comprising: acquiring a biological data set related to a scanned object; generating a first image set according to the biological data set, wherein the first image set includes a first maximum field of view image; generate one or more reference images according to the first maximum field of view image; generate a second image set according to the raw data set, wherein the second image set includes a second full-quality image; according to the one or more Generating a second bone information image from one or more reference images; correcting beam hardening artifacts of the second full-quality image based on the second bone information image; generating a first bone information image based on the one or more reference images; The first bone information image corrects beam hardening artifacts of the first full-quality image; a field of view of the first full-quality image is smaller than a field of view of the first maximum field of view image.

Description

technical field [0001] The present disclosure relates generally to computed tomography (CT), and more particularly to a system and method for correcting artifacts due to hard tissue in CT images. Background technique [0002] To provide a clear view of soft tissue, it is sometimes necessary to remove hard tissue from the CT image. However, traditional methods of hard tissue removal and beam hardening artifact correction are time consuming when two or more different CT images with different reconstruction parameters need to be generated and rectified. The present disclosure provides an efficient method and system for correcting artifacts due to hard tissue in CT images. Contents of the invention [0003] One aspect of the present invention provides a CT image reconstruction system, comprising: at least one storage medium storing a set of instructions; and at least one processor configured to communicate with the at least one storage medium, characterized in that, when exec...
