Modeling of ultrasound waves propagation in hard biological materials
such as bones and skull has a rapidly growing area of applications, e.g.
brain cancer treatment planing, deep brain neurostimulation and
neuromodulation, and opening blood brain barriers. Recently, we have
developed a novel numerical model of elastic wave propagation based on
the Kelvin-Voigt model accounting for linear elastic wave proration in
heterogeneous absorption media. So far, the model has been using
leap-frog time stepping scheme to integrate forward in time. In this
poster, we present an improved model incorporating the 4th-order
backward difference method and effect of this time-stepping scheme on
the accuracy, runtime and memory consumption of the application |
