Abstract:
1. A method, comprising: obtaining a low-resolution reference volumetric MR image of an anatomical structure of interest, such low-resolution reference volumetric MR image being distortion-resistant; obtaining a high-resolution volumetric MR image of the anatomical structure of interest, such high-resolution volumetric MR image having B0 inhomogeneous effects; registering the low-resolution reference volumetric MR image with the high-resolution volumetric MR image; calculating a distortion within the high-resolution volumetric MR image of the anatomical structure of interest based on a registration of the low-resolution reference volumetric MR image with the high-resolution volumetric MR image; and correcting the B0 inhomogeneous effects in the high-resolution volumetric MR image using the distortion.
