      abstract     = {High field MRI systems, such as 7 Tesla (T) scanners, can
                      deliver higher signal to noise ratio (SNR) than lower field
                      scanners and thus allow for the acquisition of data with
                      higher spatial resolution, which is often demanded by users
                      in the fields of clinical and neuroscientific imaging.
                      However, high resolution scans may require long acquisition
                      times, which in turn increase the discomfort for the subject
                      and the risk of subject motion. Even with a cooperative and
                      trained subject, involuntary motion due to heartbeat,
                      swallowing, respiration and changes in muscle tone can cause
                      image artifacts that reduce the effective resolution. In
                      addition, scanning with higher resolution leads to increased
                      sensitivity to even very small movements. Prospective motion
                      correction (PMC) at 3T and 7T has proven to increase image
                      quality in case of subject motion. Although the application
                      of prospective motion correction is becoming more popular,
                      previous articles focused on proof of concept studies and
                      technical descriptions, whereas this paper briefly describes
                      the technical aspects of the optical tracking system, marker
                      fixation and cross calibration and focuses on the
                      application of PMC to very high resolution imaging without
                      intentional motion. In this study we acquired in vivo MR
                      images at 7T using prospective motion correction during long
                      acquisitions. As a result, we present images among the
                      highest, if not the highest resolution of in vivo human
                      brain MRI ever acquired.},
