Endoscope (IMAGE) University of Washington Caption The UW scope looks and feels like a piece of angel-hair pasta. In this illustration, the green ball represents the bladder. The UW scope follows a spiraling path, shown with arrows, to image the whole interior. The UW software checks that the scope's path has covered the entire surface of the bladder.
