Intraoperative real—time localization of brain tumorsMajeed Kadi', Lucia Zamarano',Zhaowei Jiang', Nulte Lutz2'Wayne State University, Neurological Surgery Department2Wayne State University, Bioengineering DepartmentBS TRACTIn stereotactic neurosurgery several localizing systems suchas robotic or articulated arms and sonic digitizers cancorrelate on—site surgical points with precaptured multi—modalityimages. We discuss a strategy for intraoperative real—timelocalization of brain tumors using an opto—electronic system withlight emitting diodes (LED).2. THE MOTION ANALYSIS SYSTEMThe motion of rigid bodies, the skull—stereotactic frameunit, and various surgical instruments are tracked by the LED—based three—dimensional (3—D) motion analysis system (Optotrak 3DBar, Northern Digital, Waterloo, Canada) . |
