The purpose of the research is to establish a fast and exact deformation method of a blood vessel by considering the inner pressure. In order to reach the goal, not only the blood, which is liquid, but also the blood vessel, which is elastic body, are represented in a particle model so that the collision detection between the blood and the blood vessel is performed by a unified method that can be applied to among bloods. In addition, a fast search algorithm for neighbor particles has been developed and a blood vessel model has been generated based on medical data of a real patient. As the result of the simulation, it has been possible to perform the deformation of a blood vessel fast and exactly by considering the inner pressure.
