Abstract
We have developed a novel
methodology for the detection of arterial
mechanical properties non-invasively using
high-resolution ultrasound. The vascular
wall motion is recorded simultaneously
with the pulsatile tonometry pressure, thus
the stress-strain relationship of blood
vessel can be derived accurately. The
methodology was validated in vitro using
an elastic tube phantom as well as in vivo.
In young subjects, their dosalis-pedis
arteries (DPA) have higher distensibility
than the upper limb arteries. The DPA,
brachial artery (BA), and radial artery (RA)
have mean elastic modulus (Ep) of 1.39,
1.45, 0.90 x106 dyne/cm2 respectively; and
the mean EDRs is about 6%.
