Abstract
The present invention relates to an apparatus for detecting tumorous tissue comprising at least one excitation light source , which first excitation light source emits a first excitation light of a wavelength of between 300 nm and 314 nm and includes at least one optical fiber for guiding the first excitation light to an object field of the tissue to be examined, and at least one lens for projecting an auto-fluorescence signal and/or a remission signal of the tissue , generated by the first excitation light , to a CCD or ICCD chip of a camera , as well as a data processing system for processing the signals transmitted by the camera , said lens being capable of processing UV light and being designed such that at least two images from different spectral regions of the fluorescent object field are generated and projected to the CCD or ICCD chip, of which at least one image represents the UV range and another, different wavelength range of the auto-fluorescence signal and/or of the remission signal of said object field . The invention is further directed to a method for detecting tumorous tissue.
