PROBE APPROACH FOR DGS SIZING

摘要

An ultrasonic detection assembly detects a characteristic in a test object. The ultrasonic detection assembly includes a phased array probe positioned in proximity to a peripheral surface of the test object. The phased array probe includes a plurality of transducer elements. The transducer elements of the phased array probe transmit a sound beam into the test object. The sound beam is movable by the phased array probe within the test object to detect the characteristic. A method of detecting a characteristic in the test object with the ultrasonic detection assembly is also provided.
