Method for generating model for preoperative simulation

A method for generating a model for a preoperative simulation, comprising:

• a first step of constructing volume data for necessary organs by acquiring geometrical information from a medical image;
• a second step of manipulating said volume data to reposition and reorient an operator-designated organ to achieve a position and orientation appropriate for a surgical operation;
• a third step of generating a blood-vessel model, depicting a blood vessel to be joined to said designated organ, so as to match the position and orientation of said designated organ repositioned and reoriented in said second step;
• a fourth step of generating volume data by forming a fat model of prescribed thickness around a prescribed organ contained in said volume data constructed in said first step, after said blood-vessel model generated in said third step has been joined to said designated organ;
• a fifth step of meshing, after said fourth step, the organ represented by said generated volume data;
• a sixth step of manipulating a template model of a prescribed shape by using a template, and arranging said template model around said generated blood-vessel model;
• and
• a seventh step of generating a line-segment model based on said arranged template model.
