EXPERIMENTAL ULTRASONIC FLOW MEASUREMENT IN SMALL CAPILLARIES

In this paper we present preliminary results of an ultrasonic flow measurement set-up designed to accurately measure the flow velocity profile of blood mimicking fluid pumped through a capillary flow phantom even under the deteriorating effects of clutter and noise always seen in medical ultrasound applications. The measurement system is set up in a way to acquire and display 3-dimensional velocity and/or topological data.
