Abstract: A biological fluorescence diagnostic apparatus having a device for irradiating a biological tissue with light which excites the tissue to generate fluorescent light, and a device for taking a fluorescence image of the biological tissue passing through an ocular optical system of an endoscope. The apparatus further has a television camera unit including a television camera for taking an ordinary endoscopic observation image passing through the ocular optical system, and a television camera with an image intensifier for taking a fluorescence observation image passing through the ocular optical system after amplifying the light intensity of the image. An optical path switching system which includes a reflective surface is selectively inserted and withdrawn from the optical path of light passing through the ocular optical system so as to selectively produce ordinary and fluorescence images in the television camera unit. A filter is selectively inserted into and movable out of an illuminating light path of the endoscope in response to detection of the position of the optical path switching system.

Abstract: A bendable portion for an endoscope includes a bending mechanism which minimizes the bendable portion diameter and allows a large degree of bending. A first bending mechanism embodiment uses fluid pressure in an axially oriented chamber in a elastic body of the bendable portion. Expansion restraining members are used to restrict the expansion of the bendable portion to only the axial direction, and to protect internal members in the bendable portion. A second bending mechanism embodiment uses a shape memory alloy coil encircling the elastic body of the bendable portion. The shape memory alloy coil is heated to define the shape of the bendable portion.

Abstract: Data of ordinary color observation image obtained by picking up an object according to a RGB flame sequential system and data of fluorescent observation image obtained when the object is irradiated with excitation light are respectively transmitted to the PC. The PC calculates luminance values based on the data of ordinary color observation image to extract an area where luminance is higher than a first threshold, and extracts areas where luminance is lower than second threshold which is higher than the first threshold from the data of fluorescent observation image. The PC specifies an area which is included in both of these extracted areas, as an area having a high possibility of indicating an abnormal area.

Abstract: An endoscope system which can obtain a tomographic image in accordance with optical coherence tomography (OCT). An OCT section of the endoscope system comprises a first optical fiber, a second optical fiber, an optical coupler, a super-luminescent diode (SLD), a photodetector, and a reference mirror. The first optical fiber is opposed to the SLD at its proximal end. The second optical fiber is opposed to the photodetector at its proximal end. The optical coupler establishes optical connection between the optical fibers. The reference mirror is arranged movable in front of the distal end of the second optical fiber. The distal end of the first optical fiber is introduced to an OCT scanning unit at a tip of an endoscope. This OCT scanning unit includes a polygon mirror having a plurality of reflecting surfaces, which are tilted in different angles from each other. The OCT scanning unit forms a plurality of scanning lines aligned in parallel over a subject at regular intervals. Here, the OCT scanning unit irradiates the subject with light emitted from the distal end of the first optical fiber, and introduces the light reflected by the object to the first optical fiber.
