Endoscopy system

Abstract

The endoscope system includes: an endoscope, the insertion part of which is inserted into a predetermined organ in the subject; Detecting position information and line-of-sight information of the imaging unit; developing an image generating unit that generates a planar model image that planarly expands a model image corresponding to a predetermined organ; An image inside a predetermined organ of the information is pasted on the planar model image generated by the expanded image generation unit, and the presentation method of the planar model image is changed according to the position information.

Description

technical field [0001] The present invention relates to an endoscope system for presenting an endoscopic image using a model image of an organ. Background technique [0002] Conventionally, endoscope systems have been widely used in the medical and industrial fields. For example, in an endoscope system in the medical field, a surgeon inserts an insertion portion of an endoscope into a subject, and an endoscopic image obtained through an observation window provided at a distal end of the insertion portion is displayed on a display device. The surgeon can perform an endoscopic examination by observing the displayed endoscopic image. In addition, the endoscope system is also capable of recording endoscopic images. For example, a doctor can use recorded endoscopic images of a lesion as part of a medical record. [0003] In addition, in recent years, a capsule endoscope system has also been put into practical use. When a patient swallows the capsule endoscope, the capsule endo...

Problems solved by technology

[0008] However, it may be difficult to determine which part of the target organ the endoscopic image obtained in the previous endoscopic examination is.

[0009] In the endoscope system disclosed in Japanese Patent Application Laid-Open No. 2010-240000 as the above-mentioned first conventional example using a capsule endoscope, the endoscope image is pasted on the 3D model of the target organ. Because it is a capsule-type endoscope, doctors cannot easily grasp the position of lesion in the organ from the obtained endoscopic image

[0010] And, even in the case of an endoscope having an insertion portion, for example, sometimes it is not easy to grasp the correspondence between the designated position on the developed bladder diagram and the actual position in the bladder. The position of the lesion confirmed by endoscopic examination is recorded in such a bladder development map, and it is not easy to grasp the actual position in the bladder from the position marked in the bladder development map of such a medical record

[0011] In addition, as described above, Japanese Patent Application Laid-Open No. 2006-288869, which is a second conventional example, discloses a technique for displaying a three-dimensional image of an affected area on a monitor as an image (image) that expands the affected area planarly. However, when the insertion part of the endoscope is moved in a substantially spherical predetermined organ such as the bladder or the insertion direction is changed, it is not easy to grasp the correspondence between the image of the developed plan developed in a planar manner and the image actually taken.
