摘要： 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.

摘要： A surgical simulation model generating method includes: a first process in which a computing unit acquires geometrical information of an organ from a medical image stored in a storage unit, including an image of the organ, and generates volume data for the organ; a second process in which, after the first process, the computing unit forms nodal points by meshing the organ represented by the generated volume data; a third process in which the computing unit generates a simulated membrane that covers the organ represented by the volume data meshed in the second process; and a fourth process in which the computing unit generates a simulated organ by drawing an imaginary line so as to extend from each nodal point formed on a surface of the organ represented by the volume data meshed in the second process in a direction that intersects the simulated membrane and thereby forming a membrane nodal point at a point where the imaginary line intersects the simulated membrane generated in the third process, and by arranging on each imaginary line an imaginary inter-membrane spring that connects between the nodal point formed on the surface of the organ and the membrane nodal point, while also arranging an in-plane spring that connects between adjacent membrane nodal points on the simulated membrane.
