A major cause of Acute Coronary Syndrome (ACS) is a blood clot generated by a rupture of plaque in the coronary artery. For a diagnosis of ACS, it becomes important to characterize accurately the tissue of coronary plaque. Several methods to characterize the tissue of coronary plaque have been proposed so far. They are not however always useful due to the limitation of the performance of the features selected. In this study, we propose a new method to use sparse modeling of the 2D ultrasound signal reflected from the target tissue of plaque. The effectiveness of the proposed method has been verified by comparing the characterization results by the proposed method to those by the conventional methods for the real intravascular ultrasound data obtained from the human coronary arteries.
