Abstract:
1. A computer-implemented method comprising: acquiring, by the computer, video frames of an anatomical region of interest from a video camera optically coupled to an endoscope during an endoscopic procedure, the video frames being acquired in a sequence of instances of time; determining, by the computer, a position and orientation of a distal tip of the endoscope for each of the video frames as the video frames are acquired; associating, by the computer, each of the video frames with data indicative of the position and orientation of the distal tip as the video frames were acquired; and processing, by the computer, the video frames to produce a plurality of processed frames, to enable a user to visually navigate the video frames of the anatomical region of interest during the endoscopic procedure out of sequence using the position and orientation data associated with the processed frames, and with at least one degree of freedom that is not represented in the sequence of instances of time of the video frames acquired from the camera.
