Nuclear magnetic resonance image reconstruction method, device, storage medium and terminal equipment

Abstract

The invention provides a nuclear magnetic resonance image reconstruction method, a nuclear magnetic resonance image reconstruction device, a storage medium and terminal equipment. Under-sampled nuclear magnetic resonance images are collected. The under-sampled nuclear magnetic resonance images are input into a pre-trained nuclear magnetic resonance image reconstruction model for image reconstruction. Nuclear magnetic resonance reconstruction images are obtained. The nuclear magnetic resonance image reconstruction model is obtained through training aided by an iterator. An iterative process ofan iterator is learned in advance by using a neural network model. According to the method, the neural network model can quickly reconstruct the input nuclear magnetic resonance image according to thepre-learned nuclear magnetic resonance image reconstruction method. Parameters do not need to be adjusted in the iterative reconstruction process. The time required for reconstructing the nuclear magnetic resonance image is shortened. The efficiency of reconstructing the nuclear magnetic resonance image is improved.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to a nuclear magnetic resonance image reconstruction method, device, storage medium and terminal equipment. Background technique [0002] Magnetic resonance imaging is a non-invasive imaging technique that can provide rich information for clinical diagnosis. However, due to the constraints of magnetic resonance physics and hardware, magnetic resonance cardiac cine imaging is often limited in time and space resolution, and it is impossible to fully acquire spatial information of the scanned parts. Therefore, on the premise of ensuring the imaging quality, it is particularly important to use fast imaging methods to improve the temporal and spatial resolution of magnetic resonance cardiac cine imaging. In the prior art, usually after the under-sampled NMR image is acquired, the under-sampled K-space data is filled with spatial information through an imag...
