Problems solved by technology

[0002] Usually in magnetic resonance imaging, any voluntary or involuntary movement of the subject during the acquisition of the magnetic resonance signal will cause image artifacts, and severe motion artifacts may lead to misdiagnosis
[0003] In related technologies, the generation of motion artifacts is usually avoided by accelerating magnetic resonance data acquisition, or based on single-shot imaging methods such as echo planar imaging (EPI, Echo Planar Imaging) can be used to reduce motion artifacts, but usually Requires reduced data acquisition efficiency and is limited by lower spatial resolution

Abstract

The invention relates to a magnetic resonance image correction method and device, a medium and electronic equipment, and the method comprises the steps: obtaining initial K space data corresponding toa magnetic resonance image, and enabling the initial K space data to be multichannel data; performing multi-channel image reconstruction processing on the initial K-space data according to a down-sampling convolution kernel to obtain first reconstructed K-space data; performing multi-channel image reconstruction processing on the first reconstructed K space data according to a full-sampling convolution kernel to obtain second reconstructed K space data; correcting the second reconstructed K space data according to the initial K-space data to obtain target K space data; and performing channelcombination on the target K space data to obtain a target magnetic resonance image. Therefore, the data acquisition efficiency does not need to be reduced, the motion artifact in the magnetic resonance image can be effectively eliminated, and the effectiveness of the magnetic resonance image correction result is improved.
