Endoscope observation assistance system, method, apparatus and program

摘要

A virtual endoscope image generation unit receives, as an input, a three-dimensional medical image formed by a three-dimensional medical image formation unit, and generates a virtual endoscope image representing the body cavity viewed from a position in the three-dimensional medical image corresponding to the position of a treatment tool detected in real time by a treatment tool position detection unit. The generated virtual endoscope image is displayed on a WS display.

主权项

1. An endoscope observation assistance system comprising:
an image formation system configured to form a three-dimensional medical image representing a body cavity of a subject to be examined; a treatment tool position detection system that detects, in real time, a position of a treatment tool inserted into the body cavity and detects a direction in which the treatment tool moves straight forward at the same time as detection of the position of the treatment tool; one or more image processors configured to generate a virtual endoscope image, the one or more image processors receiving the three-dimensional medical image as an input, and generating a virtual endoscope image representing the body cavity viewed from a corresponding treatment tool position, which is a position in the three-dimensional medical image corresponding to the detected position of the treatment tool; and a display that displays the virtual endoscope image, wherein the one or more image processors generate the virtual endoscope image in which image information on a treatment tool visual line from the corresponding treatment tool position is projected, the treatment tool visual line having a direction in the three-dimensional medical image corresponding to the direction in which the treatment tool moves straight forward, the one or more image processors generate the virtual endoscope image that identifiably represents a position in the virtual endoscope image at which the image information on the treatment tool visual line has been projected, and an insertion position of the body surface at which the treatment tool is inserted into the body cavity differs from an insertion position of the body surface at which an endoscope is inserted into the body cavity.
