Problems solved by technology

[0006] However, living tissue as a target site generally has expansibility, so even if a biopsy site is specified at the time of biopsy, the insertion route to the biopsy site cannot be uniquely determined, and multiple insertion routes may be set, but in existing devices In , there is a problem that the best insertion path cannot be determined from multiple insertion paths when performing insertion support

Embodiment 1

[0056] Such as figure 1 As shown, the bronchial insertion support system 1 of this embodiment is composed of a bronchial endoscope device 3 and an insertion support device 5 .

[0057]The insertion support device 5 generates a virtual endoscopic image (hereinafter referred to as a VBS image) inside 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, and the insertion support of the bronchial endoscope device 3 into the bronchi is performed.

[0058] 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 an imaging signal from the bronchoscope, etc. The bronchoscope is inserted into the bronchus of the...

Embodiment 2

[0119] Embodiment 2 is almost the same as Embodiment 1, so only the differences will be described, and the same structures will be given the same reference numerals and descriptions will be omitted.

[0120] The route verification function 14d of the route setting unit 14 in the second embodiment has a route setting simulation function that compares the similarity between the bronchial structure of the target patient and the past bronchial structure data after the route setting is completed. The operation data on the insertion support screen 51 when the CT image data storage unit 12 has bronchial structure data similar to a predetermined similarity degree or more, and the VBS image storage unit 16 has insertion support with similar terminal positions. This can be displayed, and the insertion support simulation using the bronchial structure data and operation data can be performed, and the surgeon can more appropriately verify the set path.

[0121] Specifically, as Figure 40...

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.

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 carried out. For example, X-ray CT (Computed Tomography, computerized tomography) equipment and the like are used to take tomographic images of the subject, thereby obtaining three-dimensional image data in the subject, and using the three-dimensional image data to perform target site diagnosis. [0003] In the CT apparatus, by continuously rotating the X-ray irradiation / detection and continuously transporting the subject in the direction of the body axis, the three-dimensional area of ​​the subject can be scanned continuously in a helical shape (helical scan), according to A three-dimensional image is created by sequentially sliced ​​tomographic images of the three-dimensional region. [0004] As one of such three-dimensional images there is a three-dimensional ima...
