Abstract

In this study, an ultrasound transducer with double peak type frequency characteristics having a peak on the high frequency side for illuminating ultrasound to tissues or microbubbles in the human body and a peak on the low frequency side for detecting sub-harmonic component from microbubbles was designed with numerical calculations and fabricated as the one for sub-harmonic imaging. The trial ultrasound transducer was confirmed to have the double peak type frequency characteristics of transmitting and receiving sensitivity adapted to sub-harmonic imaging.
