Simulation of Contrast Agent Enhanced Ultrasound Imaging Based on Field II

Abstract

Abstract. Pulse-echo ultrasound signal formation can be simulated by numerical emulation of the process chain: emit signal -electromechanical emit transformation -wave propagation and scattering -electromechanical receive transformation -receive signal. The simulation software Field II is indented for simulation of linear ultrasound systems. We present an extension to Field II that enables the inclusion of nonlinear oscillations of ultrasound contrast agent bubbles into the simulation. An example is given for contrast agent enhanced imaging of a virtual vessel phantom probed by a linear array transducer.

The inertial terms in equations of motion for bubbles in tubular vessels or between plates

“…The validity of this retention will depend on, say, the degree of acoustic transmission through the tube walls along their entire length, [19][20][21][22][23][24][25][26][27] which should be recorded. The next stage must be quantitatively to examine such standard inertial terms, and this paper transparently provides researchers who consider using RP=KM-type equations with a method of doing so that clearly attributes correction factors to the inertia of the various components of the system.…”
