In this study, the relationship between exposure to ultrasound and the lifetime of microbubbles in a blood vessel model is investigated. Microbubbles are produced from a surfactant solution, and the change in the number of microbubbles upon ultrasound exposure is measured. The experimental results confirm that the microbubbles collapse upon ultrasound exposure. Microbubble lifetime is shortest when the driving frequency of the ultrasound is equal to the frequency at which the maximum value of the ultrasound attenuation of the microbubble suspension is obtained.
