    Abstract: An endoscopic system includes an endoscopic imager configured to capture image frames of a target site within a living body and a processor configured to apply a spatial transform to a preliminary set of image frames, the spatial transform converting the image frames into cylindrical coordinates; calculate a map image from the spatially transformed image frames, each pixel position in the map image being defined with a vector of fixed dimension; align a current image frame with the map image and apply the spatial transform to the current image frame; fuse the spatially transformed current image frame to the map image to generate a fused image; and apply an inverse spatial transform to the fused image to generate an enhanced current image frame having a greater spatial resolution than the current image frame. The system also includes a display displaying the enhanced current image frame.
