SYSTEMS AND METHODS FOR NAVIGATING THROUGH AIRWAYS IN VIRTUAL BRONCHOSCOPY VIEWS

摘要

PROBLEM TO BE SOLVED: To provide systems and methods for navigating through airways in virtual bronchoscopy views.SOLUTION: Systems and methods for displaying virtual bronchoscopy views while navigating through an airway of a virtual bronchoscopy comprise determining a first location and a first direction at the first location, storing the first location and the first direction in memory, displaying a first virtual camera view corresponding to the first location, determining a second location corresponding to movement through the airway of the virtual bronchoscopy, storing the second location in the memory, displaying a second virtual camera view corresponding to the second location, determining a second direction on the basis of the first location and the second location, storing the second direction in the memory, determining a third location corresponding to further movement through the virtual bronchoscopy, and determining whether the further movement is in a forward direction or a backward direction.SELECTED DRAWING: Figure 2
