Abstract
A method and device for radio-frequency field inhomogeneity correction in magnetic resonance imaging. The method includes: obtaining a first MR image by scanning a target tissue using a first pulse sequence; obtaining a B1+ field map of the target tissue; obtaining a B1−: field map of the target tissue based on the first MR image and the B1+ field map; and performing B1 field inhomogeneity correction on a second MR image of the target tissue based on the B1+ field map and the B1− field map, where the second MR image is an MR image obtained after scanning of the target tissue using any imaging protocol and any pulse sequence.
