Abstract
The invention relates to motion correction in magnetic resonance imaging (MRI), implemented as a MRI apparatus or system, computer programs for such, and a method. A motion pattern of a region of interest (ROI) is estimated by: selecting a fixed point at an anatomical position that is pre-determined to be little or not affected by motion and rotating a point in the ROI that is affected by motion on the basis of motion detected by a navigator or other methods. From the estimated motion pattern of the ROI, the field of view may be adapted by adjusting the gradients and the bandwidth of the RF pulses of the MR system in the acquisition sequence to avoid or reduce motion artefacts. Alternatively motion correction is carried out on the reconstructed images.
