Abstract

This study proposes an ultrasonic modulated sensor with an empirical physics-based model for internal carotid artery (ICA) stenosis evaluation. The model quantifies hemodynamic variations by analyzing resistance, inertia, and compliance recovery. Doppler frequency shifts, induced by blood flow, modulate the received ultrasound signal, and a frequency demodulation process extracts peak systolic velocity (PSV) for stenosis assessment. Experimental validation shows a velocity slope of 0.97 and R²=0.979, confirming strong agreement with clinical PSV trends. As stenosis increases from 5% to 95%, Rstenosis rises from 43 Ω to 945 Ω, while Lsys inertia and Cstenosis increase. The proposed actuator enables real-time, noninvasive ICA stenosis assessment in the MHz range, overcoming the limitations of existing low-frequency hemodynamic models.
