ABSTRACT:
An MR method for the reduction of motion artefacts is applicable to procedures where a plurality of MR data sets concerning an object to be examined are acquired successively in time. Because the object to be examined is liable to move during the period of time required to acquire an MR data set for the reconstruction of a high-resolution MR image, the high-resolution MR image often contains disturbing motion artefacts. In order to avoid such motion artefacts in the high-resolution MR images, first a plurality of MR data sets are acquired for low-resolution MR images; this operation can be performed within a shorter measuring period. Image transformation parameters are determined from the comparison of the low-resolution images so as to be taken into account for the reconstruction of the high-resolution MR image from the MR data sets acquired.
