description The present invention provides a method and apparatus for correcting a uniformity of a magnetic resonance image, the method including: acquiring a first uniformity enhancement image by a phased-array uniformity enhancement method; and dividing the first uniformity enhancement image by a receiving sensitivity distribution value of a body coil in a magnetic resonance imaging device, so as to acquire a second uniformity enhancement image. The method further includes: dividing the second uniformity enhancement image by a spatial signal distribution value resulting from a field strength distribution of a transmitting radio-frequency field, so as to acquire a third uniformity enhancement image.
