In hand imaging the "superman position" is stressful for the patient and therfore prone to image artifacts. In this study we used the method of cross-correlation in order to detect a contrast agent-filled sphere attached to the patient's hand. Detecting the marker very accurately and hence quantificating the amount of motion caused by three different hand-positions we identified the least stress-causing position for the patient. Herefrom it is possible to reduce the patient's shivering to a minimum and furthermore enhance image quality in high-field (7T) MR-Imaging.
