Patent number: 8413515Abstract: There is provided an ultrasonic inspection apparatus which detects various deviations with respect to an ideal scanning position and achieves, with high accuracy, an ultrasound flaw inspection by autonomously adjusting the deviations. The ultrasonic inspection apparatus according to the present invention is provided with an integrated type ultrasound transducer including an ultrasonic transducer, an integral type ultrasound transducer control unit, an actuator for distance adjustment, an actuator for tilt control, and a distance measuring sensor. The integrated type ultrasound transducer calculates a deviation between a scanning position based on a preliminarily generated scanning path information and an ideal scanning position, and performs a deviation correction processing by autonomously controlling a distance and a tilt between an opening surface of the ultrasound transducer and an inspection region of an object to be inspected in accordance with this deviation.Type: GrantFiled: February 26, 2009Date of Patent: April 9, 2013Assignee: Kabushiki Kaisha ToshibaInventors: Hideo Isobe, Hirokazu Karasawa
