Abstract:
1. A method of performing endoscopy, comprising: providing an endoscopic device comprising: an illumination device, a first imaging device, a second imaging device; and a processing system for receiving first image data from the first imaging device and second image data from the second imaging device, wherein an optical field of view of the first imaging device is larger than an optical field of view of the second imaging device; illuminating a region of interest with the endoscopic device; converting the first image data to a map of the region of interest; moving the endoscopic device in an axial direction such that the second image data is obtained at a different time than the first image data; and, registering the second image data with respect to the map, wherein the first optical field of view of the first imaging device and the second optical field of view of the second imaging device are non-overlapping; and, the map is produced by converting the first image data to 3-dimensional imaging data in cylindrical coordinates, defining a cylinder image data; and converting the cylinder image data such that the second image data is registered with respect to the map.
