In this paper, we propose a method for coronary plaque boundary calculation in Intravascular Ultrasound (IVUS) image by using a modified Perona Malik Diffusion (PMD) filter and the Takagi-Sugeno (T-S) fuzzy model. The modified PMD filter is designed based on the coronary plaque boundary direction in IVUS image to reduce the speckle noise and to enhance the coronary plaque boundary. Searching areas for the plaque boundaries are automatically set by using the weighted image separability and some heuristic rules. The coronary plaque boundaries are interpolated by the polynomials inferred by the fuzzy rules. It has been confirmed that the accuracy of the proposed method is better than that of the method using the normal PMD filter. © Springer-Verlag 2013.
