An apparatus has an anatomic positioner for migrating an anatomic part. The anatomic positioner has a mechanism for joining the apparatus to a side of a patient platform. A support member joins to the mechanism and extends longitudinally along the side. A breaking assembly moves longitudinally along the support member. The breaking assembly is operable to be fixed at a position along the support member. A support assembly is joined to the breaking assembly. The support assembly extends away from the breaking assembly and above a top of the patient platform. The support assembly positions a portion of the support assembly at a location above the top and fixes the portion at the location. A rigid member has an end portion and an engaging end. The end portion is joined to the portion of the support assembly. The engaging end engages the anatomic part and applies a pushing force thereupon.
