In this study an implementation of prospective motion correction on a 7T MR scanner is presented. The potentially higher resolution in 7T requires longer acquisition times without patient motion. The reduction of motion artefacts is shown for motion between different scans and motion during the aquisition of image data in different resolutions up to 1024x1024. The results of in vivo and phantom measurements are shown. The achievable artifact-free image resolution is limited by the accuracy of the tracking data.
