VIRTUAL ENDOSCOPIC IMAGE GENERATION DEVICE, METHOD, AND MEDIUM CONTAINING PROGRAM

摘要

A structure extracting unit extracts a structure from a three-dimensional medical image, and a view point determining unit determines a view point position and a direction of line of sight of a virtual endoscopic image. An image generating unit calculates a distance between a view point position and the extracted structure, determines a display attribute of the extracted structure based on the distance and a plurality of different display attributes that correspond to different distances from the view point position and are defined for each of the structures, and generates, from the three-dimensional medical image, a virtual endoscopic image containing the structure having the determined display attribute. A display control unit displays the thus generated virtual endoscopic image on a WS display.

主权项

1. A virtual endoscopic image generation device comprising:
an image obtaining unit for obtaining a three-dimensional image of a subject containing a plurality of structures; a structure extraction unit for extracting at least one structure from the three-dimensional image; a view point determination unit for determining a virtual view point position and a virtual direction of line of sight in a body cavity of the subject; a storing unit for storing a plurality of different display attributes that correspond to different distances from the view point position and are defined for each of the plurality of structures; and an image generation unit for determining a display attribute of the extracted structure based on a distance between the view point position and the extracted structure and the plurality of display attributes defined for the extracted structure, and generating, from the three-dimensional image, a virtual endoscopic image containing the structure having the determined display attribute viewed from the view point position in the direction of line of sight.
