Claim Text:
1. An ultrasonic detection method, comprising the steps of: providing an ultrasonic detection system having a transmitting phased array device and a receiving phased array device; positioning the transmitting phased array device and the receiving phased array device in a pitch-catch manner on a periphery of a revolutionary body and at an angle with respect to each other and with respect to the revolutionary body; and interrogating the revolutionary body in the pitch-catch manner by transmitting a phased array wave through the revolutionary body from the transmitting phased array device thereby obtaining ultrasonic detection information about the revolutionary body, the receiving phased array device not receiving the phased array wave in the absence of a reflecting feature in the path of the transmitted phased array wave, and the receiving phased array device receiving a reflected, refracted or otherwise modified phased array wave when the reflecting feature is present in the path of the transmitted phased array wave.
