Abstract

A non-invasive method for measuring the disturbances and obstructions in flow patterns inside the arterial system is a valuable tool for medical diagnostic purposes. In this study, a new high resolution Array Signal Processing technique is proposed as a diagnostic tool to employ the sounds originating from occluded arteries in determining abnormal flow conditions. In this scheme, an experiment model that demonstrates different flow conditions in constricted tubes has been built. Sounds are picked by a linear array of 16 microphones. In an experimental system, the frequency content of constricted tube is first examined before a spatial resolution is derived. Finally, the potential of the proposed approach is verified by representative computer simulations and measured results obtained in experimental model.
