  • Method and apparatus for detecting tumorous tissue
    Patent number: 6763262
    Abstract: The present invention relates to an apparatus for detecting tumorous tissue comprising at least one excitation light source 12, which first excitation light source 12 emits a first excitation light 34 of a wavelength of between 300 nm and 314 nm and includes at least one optical fiber 14 for guiding the first excitation light 34 to an object field 18 of the tissue 16 to be examined, and at least one lens 24 for projecting an auto-fluorescence signal and/or a remission signal 20 of the tissue 16, generated by the first excitation light 34, to a CCD or ICCD chip of a camera 22, as well as a data processing system 28 for processing the signals transmitted by the camera 22, said lens 24 being capable of processing UV light and being designed such that at least two images 48, 50 from different spectral regions of the fluorescent object field 18 are generated and projected to the CCD or ICCD chip, of which at least one image 48, 50 represents the UV range and another, different wavelength range of the auto-fluoresc
