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.
