Application of the Curvelet Transform on Ultrasound Images of the Carotid Artery Curvelet-based Feature Extraction and their Pathophysiological Meaning Abstract of Diploma Thesis, 2016 Stroke is a frequent disease worldwide and has enormous social and economic impact. One of the most common underlying causes of stroke is carotid atherosclerosis. Effective diagnosis requires on time and accurate estimation of carotid atherosclerosis plaque risk. The primary aim of this study was to investigate

... atures extracted from ultrasound images of the carotid artery, after the application of the Curvelet transform (CT) so as to assess the risk of plaque rupture. The features extracted were evaluated with regard to the identification and categorization of carotid plaque texture and shape characteristics. The study was specifically designed to provide the scientific community with an easy to understand pathophysiological meaning of the extracted features.
