Abstract Background Tracking of post-registration head motion is one of the major problems in frameless stereotaxy. Various attempts in detecting and compensating for this phenomenon rely on a fixed reference device rigidly attached to the patient s head. However most of such reference tools are either based on an invasive fixation technique or have physical limitations which allow mobility of the head only in a restricted range of motion after completion of the registration procedure. Methods A new sensor-based reference tool the so-called Dynamic Reference Frame DRF which is designed to allow an unrestricted 360 range of motion for the .
