Abstract

A three matching layer structure broadband medical phased array transducer was developed with 2-2 piezoelectric ceramic composite by three matching layer design scheme and KLM model optimization method. According to the design parameters, the medical phased array transducer was actually manufactured. The results show that the center frequency of actually produced medical phased array transducer was 2.95 MHz, and the relative bandwidth at -6 dB was about 83.2%, which were basically consistent with the theoretical design results (3.05 MHz, 87.8%) and met the design requirements. The transducer is expected to be used for imaging diagnosis of heart diseases.
