Abstract

A system and method for testing an acoustic probe having a series of transducer elements adapted to convert between acoustic and electrical signals is provided. The system comprises an acoustic signal generator and a receiver. The acoustic signal generator sends an acoustic signal into at least one of the series of transducer elements of the acoustic probe. An electrical transducer signal generated in response to receipt of the acoustic signal at the selected transducer element. The receiver has a switch to receive the electrical transducer signal from each selected transducer element of the acoustic probe. A display provides an illustration indicative of an operative ability of the selected transducer element of the acoustic probe to convert between acoustic and electrical signals.
