With the increasing demand for imaging in the diagnosis and treatment of musculoskeletal disorders，developing high-performance musculoskeletal ultrasound transducers，featuring higher central frequencies，wider bandwidths，higher sensitivity，and better directivity，is crucial. Traditional lead zirconate titanate（PZT）ceramics，exhibiting narrow bandwidths，complex vibration modes，and low electroacoustic conversion efficiencies，are not suitable for high-performance ultrasound transducer applications. In this study，the finite-element simulation method is used to design a musculoskeletal ultrasound array transducer based on 1-3 piezoelectric composites. The influence of the element’s area on its impedance and that of its aperture on the acoustic pressure distribution of the transducer are investigated. Finally，a physical transducer element based on the 1-3 piezoelectric composite is fabricated and tested. Test results demonstrate that the −6 dB bandwidth and central frequency of the element designed in this study are 18% and approximately 0.8 MHz higher than those for a PZT-5H transducer element having the same specifications，respectively.
