Abstract
A non-invasive method and simple apparatus for the assessment of the dynamic mechanical properties, such as stiffness, stress-strain hysteresis of the peripheral arteries is demonstrated. Clinical ultrasound B-mode and M-mode imaging are used to record the mophology and motion of peripheral vessel, and the local palpating blood pressure waveform is recorded simultaneously via external input module. Using specific ultrasound probe/pressure sensor holder and semi-automatic image-based edge-detection technique, the stress-strain loading curves of the blood vessel and the intima-media layer can be extracted. The apparatus can also examine the change of peripheral vessel mechanical properties while change the cuff pressure upstream or instantaneous phamacological treament. The nonlinear Young's module and the energy dissipation ratio resulted from the parametric analysis are early indicators for atherosclerosis and circulatory vascular diseases.
