Abstract

Systems and techniques for reducing distortions in magnetic resonance images. In one aspect, machine-implemented method for reducing image distortion in magnetic resonance imaging (MRI) includes receiving a first MRI image and a second MRI image, estimating displacements of voxels between the first MRI image and the second MRI image by minimizing a cost function expressing a cost of the displacements, reducing distortion in an MRI image using the estimated displacements, and making the MRI image having reduced distortion available. The first MRI image and the second MRI image were acquired using different gradient fields.
