Description

These ultrasound numerical phantoms mimic the systolic-diastolic cycle of i) an ideal cylindrical artery, ii) a true proper forefinger artery. The phantoms are used for validating and comparing a method for assessing the vibration-altered wall shear stress in the digital arteries. These in silico B-mode cineloops are intended to define a reference case for testing our method. In both cases, we presented also the geometry and scatters used to perform the ultrasound simulation.

Steps to reproduce

B-mode imaging is computed with FIELD II and FOCUS ultrasound simulations programs. The true artery geometry, used for working out the B-mode simulations, arises from segmented MRI images carried out on a volunteer. The walls artery displacements are simulated by a full fluid structure interaction model taking into account the blood, the artery and the surounding soft tissues.
