WIPO Patent Application WO/2016/186464
Kind Code:
A1
Abstract:
An apparatus for evaluating the performance of an ultrasonic transducer, comprises: a transducer assembly which transmits/receives ultrasonic waves by having an ultrasonic transducer and an acoustic medium; a storage unit which stores a reference signal value indicative of the performance of the ultrasonic transducer; and a processing unit which emits the ultrasonic waves by controlling the transducer assembly, receives a response (echo) signal thereto, measures magnitude or energy amount of the response signal, and compares a measured value to the reference signal value stored in the storage unit, thereby evaluating the performance of the ultrasonic transducer.
