Problems solved by technology

[0007] However, the living tissue as the target site generally has a certain range, so it is not appropriate to specify the biopsy position when using points. It is desired to specify a target area of ​​a certain size. There is a problem that the navigation path from the starting point to the target area cannot be determined

Embodiment 1

[0071] As shown in FIG. 1 , a bronchial insertion support system 1 according to the first embodiment includes a bronchial endoscope device 3 and an insertion support device 5 .

[0072] The insertion support device 5 generates a virtual endoscopic image (hereinafter referred to as a VBS image) of the inside of the bronchi based on the CT image data, and combines the endoscopic image (hereinafter referred to as a real-time image) obtained by the bronchial endoscope device 3 with the VBS image. The results are synthesized and displayed on the monitor 6, thereby supporting the insertion of the bronchial endoscope device 3 into the bronchi.

[0073] In addition, although not shown in the figure, the bronchoscope device 3 is composed of a bronchoscope having an imaging unit, a light source for supplying illumination light to the bronchoscope, and a camera control unit for signal processing the imaging signals from the bronchoscope, etc. A bronchoscope is inserted into the bronchus ...

Embodiment 2

[0107] As shown in FIG. 19 , a bronchial insertion support system 301 according to the second embodiment includes a bronchial endoscope device 303 and an insertion support device 305 .

[0108] The insertion support device 305 generates a virtual internal video image (hereinafter referred to as a VBS image) of the inside of the bronchus based on the CT image data, and combines the endoscopic image (hereinafter referred to as a real-time image) obtained by the bronchial endoscope device 303 with the VBS image. The results are synthesized and displayed on the monitor 306, thereby supporting the insertion of the bronchoendoscopic device 303 into the bronchi.

[0109] In addition, although not shown, the bronchoendoscopic device 303 is composed of a bronchoscope having an imaging unit, a light source for supplying illumination light to the bronchoscope, and a camera control unit for performing signal processing on imaging signals from the bronchoscope, and the like. A bronchoscope...

Embodiment 3

[0150] As shown in FIG. 39 , a bronchial insertion support system 501 according to the third embodiment includes a bronchial endoscope device 503 and an insertion support device 505 .

[0151] The insertion support device 505 generates a virtual endoscopic image (hereinafter referred to as a VBS image) of the inside of the bronchus based on the CT image data, and combines the endoscopic image (hereinafter referred to as a real-time image) obtained by the bronchial endoscope device 503 with the VBS image. The results are synthesized and displayed on the monitor 506 to support the insertion of the bronchoendoscopic device 503 into the bronchi.

[0152] In addition, although not shown in the figure, the bronchoscope device 503 is composed of a bronchoscope having an imaging unit, a light source for supplying illumination light to the bronchoscope, and a camera control unit for performing signal processing on imaging signals from the bronchoscope, and the like. A bronchoscope is i...

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.

Description

[0001] This application is a divisional application, the application number of the original application is 200480032336.0, the international application number is PCT / JP2004 / 016034, the application date is October 28, 2004, and the invention name is "insert support system". technical field [0002] The present invention relates to an insertion support system for supporting insertion of an endoscope. Background technique [0003] In recent years, image-based diagnosis has been widely used. For example, by taking a tomographic image of a subject with an X-ray CT (Computed Tomography) device or the like, three-dimensional image data is obtained in the subject, and the target site is diagnosed using the three-dimensional image data. [0004] In the CT apparatus, by continuously rotating and performing X-ray irradiation / detection, while continuously transporting the subject in the direction of the body axis, it is possible to perform helical continuous scanning (helical scan) in t...
