ABSTRACT:
A fluorescence diagnostic apparatus is provided in which a site to be subjected to spectrometry can be designated in an image of a diagnostic living tissue which is taken via an endoscope, and the designated site can be automatically subjected to spectrometry. Fluorescence from the inner wall of a body cavity of a patient is conveyed in an image guide fiber bundle (14) of an endoscope (10), and then emitted as parallel light from an eye lens (16a). A partial reflection mirror in a mirror box (50) allows most of the light to transmit therethrough, and reflects the other portion of the light. From the transmitted light, an image of the inner wall of the body cavity is formed by an imaging lens. The image is taken by a fluorescence-observation CCD (34), and displayed by a display of a video monitor device (60). On the other hand, from the light reflected by the partial reflection mirror, an aerial image of the inner wall of the body cavity is formed by an imaging lens. A touch panel is disposed on the display of the video monitor device (60). When a part of the touch panel is pressed, the tip end of a spectrometry-fiber probe of a spectroscope (39) is moved by an X-Y table (31) to a position in the aerial image which is equivalent to the pressed site of the touch panel.
