Abstract
Disclosed in the present embodiments are a method and a device for correcting a shimming device. A phase image in a coronal plane direction of a phantom is used to make an estimation of a degree of symmetry of the phase image for each test position of the shimming device. From the image symmetry estimation result corresponding to each test position, a test position with the best image symmetry estimation result is selected to be an optimum deployment point of the shimming device.
