Three-dimensional surface reconstruction of the coronary arterial from intravascular ultrasound (IVUS) images plays an important role in diagnosis and treatment of the atherosclerosis. A simplified 3-D topologically adaptable snake model (3-D T-snake) is proposed; nevertheless, it can successfully address the significant problem of conventional T-snakes when dealing with the model self-intersections. A method of surface reconstruction of IVUS coronary arterial walls based on the simplified 3-D T-snake is presented. The experimental results indicate that the method is accurate and robust, and the simplified 3-D T-Snake is feasible and valid.
