Abstract: Ultrasonic transducer（also called ultrasonic probe） is one of the key components of medical ultrasound equipment,its characteristics of good or bad direct impact on the performance of even limited to the entire device. With the continuous development of piezoelectric materials and Micro-electromechanical Systems（MEMS） technology,small size,light quality,high frequency band,high resolution,high frequency,high sensitivity will be the future development of medical ultrasonic transducer. Summary of current domestic and international high-frequency medical ultrasound transducer application development,focusing on the main issues of their differences and the status of development at home and abroad,and prospects for its future development trend according to the status of high-frequency medical ultrasound transducer.
