摘要： A method of manufacturing an ultrasound transducer is provided. The ultrasound transducer is activated and the activity across the transducer is measured to determine whether the activity at any area does not meet an acceptance criteria. The transducer is then modified so that the area meets the acceptance criteria. The transducer may be modified with a laser which removes material from the area which does not meet the acceptance criteria.
