3D time domain numerical code developed
March 22nd, 2005
A 3D time domain numerical code has been developed, and may shed new light on the mechanics of diagnostic ultrasound. According to recent research from the United States, a "time domain numerical code (the so-called Texas code) that solves the Khokhlov-Zabolotskaya-Kuznetsov (KZK) equation has been extended from an axis-symmetric coordinate system to a three-dimensional (3D) Cartesian coordinate system." "The code accounts for diffraction (in the parabolic approximation), nonlinearity and absorption and dispersion associated with thermoviscous and relaxation processes," explained X.M. Yang and coauthors at Boston University. "The 3D time domain code...
