A fixed array of NMR field probes has proved to be a valid tool for monitoring the effects of a wide range of head movements in a 7T scanner. Here, we use this set up to detect significant field changes in order to give early feedback on head motion. This information could be used in deciding to stop a scan or to reacquire all or part of the k-space data in order to avoid acquisition of motion corrupted image data. This method can be implemented without requiring image sequence modification nor rigid coupling of a motion marker to the head.
