Phase correction method and device, computer equipment and storage medium

The invention relates to a phase correction method and device, computer equipment and a storage medium. The method comprises the following steps: pre-scanning a target object through magnetic resonance to obtain a plurality of echo data, determining reference echo data and to-be-corrected echo data according to the plurality of echo data, determining a correction phase difference according to the reference echo data and the to-be-corrected echo data, and then performing phase correction on the to-be-corrected echo data by using the correction phase difference to obtain the corrected echo data. And obtaining corrected echo data corresponding to the echo data to be corrected. According to the method, deviation correction is carried out based on the reference echo data, phase information between different channels and phase information between water and fat contained in the echo data are reserved, and therefore a reliable data basis is provided for reconstructing a magnetic resonance image based on the important
