Abstract

The present application relates to a magnetic resonance imaging method, device, computer equipment and storage medium. The method includes: acquiring a magnetic resonance imaging signal corresponding to the detection site, the magnetic resonance signal is obtained by multiple excitations of the detection site excitation imaging sequence; encoding the magnetic resonance signal, obtaining K-space data corresponding to the magnetic resonance signal, and converting the magnetic resonance signal to The K-space data corresponding to the signal is used as the K-space data to be corrected; the K-space data to be corrected is input to the preset neural network for phase correction, and the phase-corrected K-space data is obtained; the phase-corrected K-space data is reconstructed to obtain the detection The corresponding magnetic resonance images. The imaging efficiency can be improved by adopting the method.

Description

technical field [0001] The present application relates to the technical field of medical imaging, in particular to a magnetic resonance imaging method, device, computer equipment and storage medium. Background technique [0002] Magnetic resonance equipment is a kind of medical imaging equipment that uses the spin motion of atomic nuclei to generate magnetic resonance signals after being excited by radio frequency pulses in an external magnetic field, and performs imaging based on magnetic resonance signals. The magnetic resonance signal contains the tissue information of the whole excitation range, which is a comprehensive magnetic resonance information signal. In order to obtain a certain layer and the magnetic resonance signals at different positions in the layer, it is necessary to use linear gradients to encode the tissue space, including layer direction coding, frequency and phase direction coding. Encoding is to superimpose a linear gradient field on the original mag...
