Simulation of ultrasound interaction with tissue

摘要

We model the effect of an ultrasound beam on a water phantom by considering water as an incompressible Newtonian viscous fluid. The two-dimensional flow velocities (u,v) induced in the water phantom, mimic displacement in living tissues for a phantom of unit width. The displacements depend on the ultrasound signal which is emitted and the model also predicts the nature of the signal received. 13 refs, 3 figs. (Atomindex citation 26:078040)
