SYSTEMS AND METHODS FOR NAVIGATING THROUGH AIRWAYS IN A VIRTUAL BRONCHOSCOPY VIEW

摘要

Systems and methods for displaying virtual bronchoscopy views while navigating through an airway of a virtual bronchoscopy are disclosed. The method comprises 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 based on 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.

1. A method for displaying virtual bronchoscopy views while navigating through an airway of a virtual bronchoscopy, the method comprising:
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 based on 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; if it is determined that the further movement is in the forward direction:
displaying a third virtual camera view corresponding to the third location; and if it is determined that movement is in the backward direction:
retrieving the stored first direction and the stored second direction from the memory;determining a smoothing vector based on the stored first direction and the stored second direction;obtaining a smoothed virtual camera view based on the smoothing vector; anddisplaying the smoothed virtual camera view.
