Diagnosis apparatus for the picture providing recording of fluorescing biological tissue regions

A diagnosis apparatus for picture recording of fluorescing biological tissue regions comprising:

• a light source coupled to a filter arrangement for emitting at least one spectral region to effect fluorescence stimulation in tissue;
• optics for receiving and guiding fluorescent light reflected by the tissue;
• a video camera for recording pictures of at least two spectral regions of the fluorescence light reflected by the tissue and guided by the optics;
• and
• picture processing means for processing picture information of the pictures recorded by the video camera of the at least two spectral regions, and producing in at least two separate channels color-separate picture signals serving the diagnosis of the tissue region to be examined;
• wherein the video camera comprises a single, highly sensitive, black and white CCD solid body camera and a color splitter for disaggregating the at least two spectral regions of the received light into a first picture region allocated to the color green and a second picture region spatially separated therefrom and allocated to the color to be received on the black and white CCD solid body camera;
• the picture processing means time-sequentially receives the spatially separated picture regions on the CCD solid body camera and delays them against one another in separate channels such that the picture signals are simultaneously outputted and are inputted to an RGB color monitor to produce a mixed-color monitor picture.
