Fractal simulation of coronary arteries based on bifurcate rule-base

As to the research of 3D reconstruction in modern medical imaging, if an object to be reconstructed can be simulated by computer, its X-ray projections will be gotten exactly and freely, which will be more significant in testing the behaviour of reconstruction algorithms. In this paper we present a new, efficient method to simulate coronary arteries under the background of cone-beam reconstruction. In order to achieve this task, we create a bifurcate rule-base of coronary arteries and model their spatial configuration by controlling the parameters in spherical coordinates, then we use random iterated algorithm to simulate them by the reference of fractal theory.
