Abstract
The invention is directed to the provision of a method for generating a model for a preoperative simulation, wherein the method includes: a first step of constructing volume data for necessary organs by acquiring geometrical information from a medical image; a second step of manipulating the 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 the designated organ, so as to match the position and orientation of the designated organ; a fourth step of generating volume data by forming a fat model of prescribed thickness around a prescribed organ contained in the earlier constructed volume data, after the blood-vessel model has been joined to the designated organ; a fifth step of thereafter meshing the organ represented by the generated volume data; a sixth step of manipulating a template model of a prescribed shape by using a template, and arranging the template model around the generated blood-vessel model; and a seventh step of generating a line-segment model based on the thus arranged template model.
