Prospective motion correction techniques have been shown to be beneficial in less compliant patient populations. The image-based PROspective MOtion (PROMO) correction performs best if navigators are optimally placed with respect to the anatomy. This work describes a new technique to automatically position the navigators based on an automatic scan planning algorithm that uses a rapid implicit symmetry axis determination.
