三维声波散射的时域仿真
Time Domain Simulation of Three Dimensional Acoustic Scattering
摘要
Abstract
In order to study the dynamic wave scattering in medical ultrasonic diagnosis, the finitedifference time domain method is applied to solve the three-dimensional acoustic scattering in time domain.Three-dimensional model of the velocity-stress staggered-grid finite-difference on acoustic waves has been established. The construction of perfectly matched layer (PML) is discussed, and the finite-difference scheme of the PML boundary conditions is implemented. The property of the PML is analyzed. Active simulation of the scattering of standard three-dimensional object has been finished. Numerical experiments have proved the effectiveness of the proposed algorithm.关键词
