Patent number: 8019405Abstract: A device for picture-providing diagnosis of tissue is selectively operated in a picture-providing white light diagnosis mode and a picture providing auto-fluorescence mode. A color camera having red, green, and blue sensors provides a monitor which picture signals. A light source emits fluorescence excitation light and additionally emits so much red light that the red light remitted by the tissue dominates the red fluorescence light in the picture providing auto-fluorescence mode. The signal from the red sensor of the camera is damped so that normal time appears green and pre-malignant and early malignant tissue appears red.Type: GrantFiled: April 4, 2002Date of Patent: September 13, 2011Assignee: Richard Wolf GmbHInventors: Bernd Claus Weber, Thomas Goll, Olaf Schmidt, Philipp Eidner, Stefan Müller, Hubert van den Bergh, Didier Goujon, Georges Wagnières
