Journal ArticleDOI
Modeling of nonlinear ultrasound propagation in tissue from array transducers
TL;DR: A computationally efficient model capable of simulating finite-amplitude ultrasound beam propagation in water and in tissue from phased linear arrays and other transducers of arbitrary quasiplanar geometry is described, based on a second-order operator splitting approach.
Journal ArticleDOI
Modeling of pulsed finite-amplitude focused sound beams in time domain.
TL;DR: A time-domain numerical model is presented for simulating the finite-amplitude focused acoustic pulse propagation in a dissipative and nonlinear medium with a symmetrical source geometry that allows for arbitrary absorption and dispersion and makes use of full diffraction formulation.
Journal ArticleDOI
Numerical modeling of finite-amplitude sound beams: Shock formation in the near field of a cw plane piston source
TL;DR: In this article, two theoretical models and corresponding numerical codes for the description of nonlinear acoustic beams radiated from intense cw sources in water are presented, and the results of modeling obtained by both codes are compared with each other and with known experimental data, and are found to be in a good agreement.
Journal ArticleDOI
Sources of error in maximum velocity estimation using linear phased-array Doppler systems with steady flow.
TL;DR: It was found that the effect of transducer focal depth, intratransducer, intramachine, intermachine and beam-steering did not significantly contribute to maximum velocity estimation errors, and the dependence of the maximum velocity on the Doppler angle made the greatest contribution to the estimation error.
