Abstract
A method and system related to phased array ultrasonic systems identifies faults in individual element on a regular basis. The method and system are based on a simple approach of calculating energy levels in response signals from each individual element and then identifying any discontinuities or unexpected drops in energy levels sensed during a typical phased array operation, by comparing responses for individual transducer elements to the group response.
