Title:
MAGNETIC RESONANCE IMAGE RECONSTRUCTION METHOD AND APPARATUS, DEVICE, AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/077557
Kind Code:
A1
Abstract:
A magnetic resonance image reconstruction method and apparatus, a device, and a medium. The method comprises: acquiring under-sampled magnetic resonance data (S110); and inputting the magnetic resonance data into an image reconstruction model based on an alternating direction method of multipliers (ADMM) algorithm to obtain a reconstructed target magnetic resonance image, wherein the image reconstruction model is a model obtained by generalizing an iterative relation expression after decomposing an original image reconstruction model and iteratively solving same (S120). The method solves the problem that in the process of decomposing an original image reconstruction model and iteratively solving same, a parameter of an input item in the solution of each sub-problem after decomposition is determined on the basis of an empirical value, which cannot be applied to all image reconstruction conditions, thereby improving the image quality after image reconstruction based on the ADMM algorithm.
