摘要： PROBLEM TO BE SOLVED: To generate a simulation model adapted to the situation of an operation, from a medical image.
SOLUTION: Geometric information is acquired from the medical image to construct volume data of a required internal organ. The volume data is operated to form the position and attitude of the internal organ specified by an operator, into a position and an attitude adapted to the operation. A blood vessel model connected to the specified internal organ is generated according to the position and attitude of the specified internal organ. A fat model of predetermined thickness is imparted around the predetermined internal organ included in the volume data in the connected state of the blood vessel model, to generate volume data. The internal organ in the generated volume data is then meshed. A template model of predetermined shape is operated using a template and arranged around the generated blood vessel model. A segment model is generated based on the arranged template model.

摘要： PROBLEM TO BE SOLVED: To achieve determination of a trocar port in simulation under endoscope. SOLUTION: A segmentation part constituted by a computer extracts an organ from imaged data imaged at prescribed intervals in a living body. The imaged data of the organ imaged at prescribed intervals are laminated to configure three-dimensional volume data. An image generation means reads out the three-dimensional volume data to form an image so as to view the living body from a virtual view point to display the image on a monitor screen. A prescribed number of trocar port positions are designated on the displayed living body surface. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To achieve, with a simple, small, and light-weight mechanism, a holding reaction force of forceps as a simulation tool in an endoscope surgery simulation by computer graphics, and to present a surgery simulation without causing discomfort.SOLUTION: An internal member is disposed in a long-sized cylindrical member movably in the lengthwise direction. Moving/driving force transmitting means connected to the internal member is disposed at the rear end of the cylindrical member, and moves the internal member in the lengthwise direction in the cylindrical member. A holding mechanism can bring a contact member into contact with the internal member through openings formed in both facing side surfaces in an intermediate part of the cylindrical member. The contact force of the contact member is controlled in response to the holding state of the forceps in a surgery simulation, thereby simulating the holding reaction force of the forceps.
