Claim Text:
1. An ultrasonic detection assembly for detecting a characteristic in a test object, the ultrasonic detection assembly including: a phased array probe positioned in proximity to a peripheral surface of the test object, the phased array probe including a plurality of adjacent transducer elements collectively configured to provide an inspection surface extending substantially parallel to a direction along which the test object extends, each transducer being operatively configured to emit a respective beam into the test object so as to provide a pattern of constructive interference such that the phased array probe is providing a single, rotationally symmetric sound beam into the test object, the phased array probe being configured to move the sound beam within a range of angles from the phased array probe and bounded by a first beam position extending in a first direction from the phased array probe and a second beam position extending in a second, different direction from the phased array probe within the test object to detect the characteristic.
