    A novel computer modeling and simulation technique for bronchi motion tracking in human lungs under respiration

    In this work, we proposed a novel computer modeling and simulation technique for motion tracking of lung bronchi (or tumors) under respiration using 9 cases of computed tomography (CT)-based patient-specific f...
