The problem of motion in MRI scan still remains prevalent for many applications and numerous solutions for motion correction in MRI have been proposed to improve the image quality in presence of motion. Prospective motion correction using an optical tracking system has the advantage that it allows to eliminate motion artifacts without prolonging the overall scan time. In this study, we scanned healthy subjects at 7T with high resolution structural imaging sequences for diverse range of contrasts, which are commonly used in neuroscience applications. The final results show an improved image quality and a great potential of prospective motion correction.
