Problems solved by technology

Under the action of the neural network, the output picture will be infinitely close to the fully sampled image, but due to the missing details of the undersampled image itself and the randomness of the neural network, some details may still be missing or added.

Abstract

The invention provides a magnetic resonance image reconstruction method, comprising the following steps of acquiring undersampled k-space data; obtaining a prediction image based on the trained neuralnetwork model and the undersampled k-space data; and generating a reconstructed image based on a compressed sensing algorithm, the undersampled k-space data and the predicted image, wherein the compressed sensing algorithm includes a plurality of constraint terms, at least one of the constraint terms includes the predicted image.

Description

technical field [0001] The present invention mainly relates to the field of medical images, in particular to a magnetic resonance image reconstruction method, device and computer-readable storage medium. Background technique [0002] Medical images, especially computed tomography (CT, Computed Tomography), positron emission tomography (PET, Positron Emission Tomography) and magnetic resonance images (MR, Magnetic Resonance) are all very important medical images, which can non-invasively provide patients with Anatomical structure images, thus providing effective technical support for the diagnosis of related diseases. [0003] For example, the information collected by MR imaging equipment is converted into a grayscale image that can be recognized by doctors after going through image reconstruction algorithms, image preprocessing and other steps. Magnetic resonance imaging can provide excellent images of soft tissues, but the imaging speed is relatively slow due to the series...
