Abstract: An image processing device having a very straightforward construction, for obtaining an image in which normal tissue and diseased tissue are easy to identify, comprises: an image synthesizing section that generates a synthesized image by synthesizing an image signal of reflected light image produced by illumination light obtained by illuminating body tissue with illumination light and an image signal of a fluorescent image obtained by illuminating the body tissue with excitation light; and a gain adjustment section that adjusts the gain of the image signal of the reflected light image and/or the image signal of the fluorescent image such that the boundary of the hues of the normal tissue and diseased tissue found from the optical characteristics of the respective tissues is contained in a predetermined range with respect to a prescribed standard chromaticity diagram, depending on whether the body tissue that is displayed on the synthesized image generated by the image synthesizing section is normal tissue or diseased tissue.

Abstract: An insertion support system comprises a VBS image producing part for producing, on a frame-by-frame basis, successive VBS images of a route established, based on CT image data, by a route establishing part; an image processing part for producing an insertion support display including a live image, a VBS image and multiple thumbnail VBS images; and a memory for linking, with the frame information of the VBS image, and storing rotational angle data of the VBS image based on an input signal from an input part. The image processing part rotation corrects, based on the rotational angle data of the VBS image stored in the memory, the VBS image and thumbnail VBS images to produce insertion support images. This arrangement can produce virtual endoscope images, at a plurality of branching points of a bronchus, corresponding to a bronchus insertion operation, thereby effectively supporting the insertion of the bronchus endoscope.

Abstract: An insertion support system in which upon designation of a biopsy area in a bronchial end portion, a center of gravity of the biopsy area is spotted. A circle around the center of gravity is designated as a search area. The search area is expanded until the bronchi position within the search area. The point at which the bronchi have for the first time positioned in the search area is designated as a final point. A first route candidate joining a start point with this final point is determined. This first route candidate, if not yet registered, is registered as a first registered route. Thus, any site concerned can be specified by an arbitrary region, and a navigation for reaching the specified region can be appropriately set up.

Abstract: With a bronchial tube insertion support system according to the present invention, a route setting unit comprises a route starting-point setting function for setting the insertion starting-point of a bronchial tube, a region-of-interest setting function for setting a region of interest serving as the insertion end-point of the bronchial tube, a route extracting function for extracting an insertion route from an insertion start point to an insertion end point, and a route verifying function for performing verification of the extracted insertion route. According to these functions, of multiple insertion routes, the most appropriate insertion route when performing insertion support is determined.

Abstract: An analysis section (9) is connected to an insert operation information collection section (5), an endoscope video output section (6), and a processing device (2) so as to be provided with live insert operation information and an endoscope image as well as insert operation information as a reference of the storage information and an endoscope image related to this operation information (an endoscope image picking up an examinee of the insert portion end position detected by the insert operation information). While an operator operates a bronchia endoscope, the analysis section (9) collects in real time the insert operation information from the insert operation information collection section (5) and the endoscope video output section (6) and an endoscope image and successively compares for analysis the collected insert operation information and the endoscope image to the insert operation information and the endoscope image as the related reference which is the storage information stored in a storage section (2A) of the processing device (2). The comparison result is output to a notification section (10) so as to monitor the insert operation of the endoscope insert portion by the operator.

Abstract: An endoscope (1) uses a navigation screen (51) consisting of an endoscope live image display area (52) for displaying a live image from a bronchoscope (2), a VBS image display area (53) for displaying a VBS image, and a branched thumbnail VBS image area (54) for displaying reduced VBS images at all the branching points in the route as branched thumbnail VBS images. Thus, it is possible to navigate the endoscope accurately at the target portion according to the guide image corresponding to the actual branching position.
