Real Time IVUS Segmentation and plaque characterization by combining Morphological Snakes and Contourlet Transform

M. A. Hamdi, M. A. Mrabti


After the principal custom of the technics of intravascular ultrasound (IVUS) as an imaging technique for the coronary artery system 70th century until nowadays , the segmentation of the arterial wall boundaries and plaque characterization still an imperative problem . Much research has been done to give improved segmentation result for better diagnostics , therapy planning and evaluation. In this paper we present a new segmentation technics by combining Contourlet transform and Morphological Snakes which developed by Luis Alvarez used for IVUS segmentation followed by plaque characterization . The morphological snakes associate the morphological and differential operators used in the standard PDE based snake models. Results are presented and discussed in order to demonstrate the effectiveness of this approach in IVUS segmentation.
