The measurement of blood volume flow is critical in many clinical applications. The current state-of-the-art for volume flow quantification uses pulsed-wave ultrasound, using a method that is neither accurate nor reliable. In this work, we implemente

Background Acute ischemic stroke is often due to thromboembolism forming over ruptured atherosclerotic plaque in the carotid artery (CA). The presence of intraluminal CA thrombus is associated with a high risk of thromboembolic cerebral ischemic even
