Surgeons navigating lungs with 3-D maps

Miami Herald, January 8, 2008
Surgeons at University of North Carolina-Chapel Hill are using electromagnetic seeds to make landmarks in lungs to help them perform more accurate biopsies for patients facing cancer. The system begins with the patient having a special CT scan that is used to create a 3-D map of the lungs. The map is used to chart the quickest route to nodules in the lungs, while electromagnetic seeds are placed to mark the way.
