Abstract

This paper describes a method for measuring extinction coefficients of a microbubble suspension at different probing pulse pressures. The experimental results demonstrated the usefulness of this method for evaluating acoustic properties of microbubbles of ultrasound contrast agents and also for finding the optimum exposure conditions of ultrasound.
