Abstract
The optimization of ultrasonic transducer performances is generally tackled in the manufacturing stage and defines the upper limit of the obtainable performances. Nevertheless in many practical applications in medical imaging and non destructive testing the transducer is poorly matched with the front end electronics and the transducers’ characteristics are not fully exploited1,2,3. The transducer characteristics can be preserved if an effective model of the actual transducer is available to the electronic designer. Aimed to this problem, this paper presents a new method for ultrasonic transducer modelling. This method provides an input-output analytical model of the ultrasonic transducer and the model is built without a priori knowledge of the manufacture characteristics. In this way we consider the transducer as a two-port blackbox, wholly characterized by the electrical driving-point impedance and the acousto-electric transfer function.
