Abstract
The invention relates to a method of MR imaging of an object () placed in the examination volume of a MR device (). It is an object of the invention to provide a method that enables efficient motion-compensation and/or motion-correction and that is compatible with Cartesian sampling of k-space. The method of the invention comprises: —generating MR signals by subjecting the object () to a MR imaging sequence of at least one RF pulse and switched magnetic field gradients; —acquiring the MR signals as a plurality of temporally successive subsets, each subset comprising a number of k-space profiles with sub-sampling of k-space, wherein the subsets complement each other to form a fully sampled set of k-space profiles; —reconstructing a single-subset MR image from each subset; —computing a gradient MR image from each single-subset MR image; and —detecting motion by comparing the gradient MR images with each other. Moreover, the invention relates to a MR device () and to a computer program for a MR device ().
