Abstract
A magnetic resonance imaging system () includes a radio-frequency system () with multiple coil elements () for acquiring magnetic resonance data () and a memory () for storing machine executable instructions () and pulse sequence commands (). The pulse sequence commands are configured for controlling the magnetic resonance imaging system to acquire the magnetic resonance data according to a SENSE imaging protocol. Execution of the machine executable instructions causes a processor () to: control () the magnetic resonance imaging system to acquire the magnetic resonance data using the pulse sequence commands; reconstruct () a set of folded magnetic resonance images () from the magnetic resonance data; calculate () a voxel deformation map () from a magnetic field inhomogeneity map; and calculate () a set of unfolding matrices () using a least partially a coil sensitivity matrix () for the multiple coil elements, wherein the set of unfolding matrices includes at least one modified unfolding matrix which is calculated at least partially using the a coil sensitivity matrix and the voxel deformation map. Undistorted magnetic resonance image data () is calculated () using the set of folded magnetic resonance images and the set of unfolding matrices.
