Abstract

Oscillation of a microbubble under an ultrasonic wave produces a secondary ultrasonic wave around the bubble. In this paper, a novel method for reconstructing a secondary wave source map is proposed. A holographic method is adopted in order to derive both the amplitude and phase maps of secondary ultrasonic wave sources. Experiments are carried out using microbubbles produced by an ultrasonic wave contrast agent.
