Title:
IMAGE RECONSTRUCTION METHOD AND APPARATUS, ELECTRONIC DEVICE AND MACHINE-READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/120899
Kind Code:
A1
Abstract:
An image reconstruction method, comprising: executing the following cycle processes until end conditions of a cycle are met: filtering image data and data residuals of a target image during a previous cycle process on the basis of a target image structure filter so as to obtain first image data during a present cycle process (S110); filtering target image data and data residuals during the previous cycle process on the basis of a guide image structure filter so as to obtain second image data in the present cycle process (S120); obtaining the image data of the target image during the present cycle process according to the first image data and the second image data (S130); obtaining the data residuals during the present cycle process according to undersampled data in a K space, the image data of the target image during the present cycle process and the target image data and data residuals obtained during the previous cycle process (S140); when the end conditions of the cycle are not met, the image data and data residuals of the target image during the present cycle process serve as the image data and data residuals in the next cycle process.
