Abstract:
An arrangement for diagnosing malignant tissue by fluorescence observation, comprising an endoscope (1), a white light source (3, 16, 37), a fluorescence stimulator (4, 35) for emitting a light beam, and an analyzer (5, 15, 43), wherein the fluorescence stimulator (4, 35) constantly emits a continuous light beam during a diagnosis, the white light source (3, 16, 37) comprises a device for effecting a periodic change of intensity of a visible light pulse emitted from the white light source (3, 16, 37), and the analyzer (5, 15, 43) is activated when the intensity of the visible light pulse approaches zero and is deactivated during emission of the visible light pulse.
