The choice of viscous or viscoelastic models affects attenuation and velocity determination in simplified skull-mimicking digital phantoms.
Samuel Clinard, Taylor Webb, Henrik Odéen, Dennis L. Parker et autres
Objective: Simulation-guided transcranial focused ultrasound therapies rely on accurately estimating the skull's acoustic properties with pretreatment imaging. The typical imaging resolution (0.5 mm isotropic) is insufficient to resolve the bone microstructure, and as a result, the acoustic properties are underdetermined. Consequently, the …
