Accurate measurement of wall thickness is crucial in arterial shear wave elastography to prevent significant errors in estimating mechanical properties.
Accurate wall thickness measurement is essential to limit elastography errors; animal data leave open clinical translation.
= 0.82 ± 0.04 for hollow cylinders). Wall thickness had a larger effect than diameter on the dispersion curves, which did not have major effects above 400 Hz. An underestimation of 0.1-0.2 mm in wall thickness introduces an error 4-9 kPa in hollow cylinders with shear modulus of 21-26 kPa. Therefore, wall thickness should correctly be measured in arterial SWE applications for accurate mechanical properties estimation.
