Problems solved by technology

[0006] 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

[0070] Such as figure 1 As shown, the bronchial insertion support system 1 of the first embodiment is composed of a bronchial endoscope device 3 and an insertion support device 5 .

[0071] 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.

[0072] 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 bron...

Embodiment 2

[0106] Such as Figure 19 As shown, the bronchial insertion support system 301 of the second embodiment is composed of a bronchial endoscope device 303 and an insertion support device 305 .

[0107] 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.

[0108] 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 bronch...

Embodiment 3

[0149] Such as Figure 39 As shown, the bronchial insertion support system 501 of the third embodiment is composed of a bronchial endoscope device 503 and an insertion support device 505 .

[0150] 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.

[0151] 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 bronchoscop...

Abstract

According to an insertion support system of the present invention, when a biopsy area is specified at a periphery of the bronchi, the barycenter of the biopsy area is extracted. A circle centering on the barycenter is determined as a search area. The search area is expanded until the bronchi are located within the search area. A point in the search area to which the bronchi first reach is determined as an end point. A first route choice connecting the end point and a start point is determined. If the first route choice has not been registered yet, the first route choice is registered as a first registered route. Accordingly, a location of interest can be specified as an arbitrary region, and navigation leading to the specified region is appropriately set.

Description

technical field [0001] The present invention relates to an insertion support system for supporting insertion of an endoscope. Background technique [0002] 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. [0003] 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 the three-dimensional area of ​​the subject , generating a three-dimensional image from consecutive slice tomograms of the three-dimensional region. [0004] One such three-dimensional image is a three-dimensional image of the bronchi of the lungs. The three-dimensional imag...
