The simulation of catheter, guide wire, rigid tissues, muscles and blood vessels using conventional methods like mass spring model and FEM are computationally expensive. The former is comparatively faster than the latter but less accurate. Earlier, we proposed a new method of simulating of tubular organs using deformable beam models. This method is not only accurate but also promises to be faster than mass-spring model for the simulation of tissues. This paper focuses on an important aspect of this approach--the determination of key and driving points of a beam model.
