Cardiac Structure Recognition in Ultrasound Images

The paper presents a research on detection of cardiac structures in echocardiography gray images from fetal hearts. Pattern recognition and a density probability function of scales of gray is used for search cardiac structures and then compared with pattern structures previously stored. The Bhattacharyya coefficient is used in order to obtain the similarity to define the choice of the structures of interest. The method uses also texture features to isolate the region of interest inside the ultrasound image to improve the results and performance. The prototype developed to evaluate the method and some validated results are presented.
