Hybrid Model of Ultrasonic Transducer for better Medical Imaging

Recently, ultrasound becomes prominent in several applications especially in medical field to improve the health services either for diagnostic. The emergence of ultrasound applications raises the need of reliable transducer to comply with that purpose. As polymer material being popular in medical ultrasound, there are chances to combine it with former piezoelectric ceramic material in designing diagnostic transducer to get hybrid characteristics required for multi-frequency application. In this work, SPICE model of ceramic-polymer piezoelectric has been described. With signal conditioner circuit, complete analog system for ultrasound has also been developed.
