An ultrasonic inspection apparatus includes: an ultrasonic probe apparatus including an ultrasonic transducer; a drive element selecting section that selects a required piezoelectric vibrator of the ultrasonic transducer; a signal detecting circuit that detects an electric signal dependent on a reflected echo of an ultrasonic wave emitted from the selected piezoelectric vibrator; a signal processing section that produces data on an internal image of the inspection object based on the detected reflected echo; a second display unit that combines multiple pieces of image data acquired from the signal processing section and displays an integrated visualization data result; and an second input unit that is used to perform an operation command such as a command input to start or terminate an inspection or an a command to set inspection condition.

Ultrasonic inspection apparatus, ultrasonic probe apparatus used for ultrasonic inspection apparatus, and ultrasonic inspection method

An ultrasonic transducer is provided with a distance measuring ultrasonic sensor for detecting a distance between the ultrasonic transducer and a surface of an inspection object and an inclination of the ultrasonic transducer with respect to the surface of the inspection object, to control the distance and the inclination of the ultrasonic transducer with respect to the inspection object based on information detected by the distance measuring ultrasonic sensor, and at least part of ultrasonic wave transmission/reception by the distance measuring ultrasonic sensor is performed during execution of aperture synthesis processing during which transmission/reception by the ultrasonic transducer is not performed.

Ultrasonic inspection device and ultrasonic inspection method

There is provided an ultrasonic inspection apparatus using scanning path information with high accuracy at a time of ultrasonic flaw inspection. The ultrasonic inspection apparatus includes: a measurement unit measuring a distance to a surface of the object to be inspected to obtain measurement data including a group of points; a shape data generation unit, by using the measurement data including the group of points obtained by the measurement unit, for generating shape data of the surface of the object to be inspected including the group of points having position information represented by a coordinate system of the scanner mechanism; and a path information generation unit, by using the shape data generated by the shape data generation unit, for calculating a passage point on the surface of the object to be inspected that forms a scanning path of the ultrasonic transducer, and generating the scanning path information of the ultrasonic transducer in which a normal vector of the passage point on the surface of the object to be inspected and an opening surface of the ultrasonic transducer intersect each other, and a distance between the passage point and a center of the opening surface of the ultrasonic transducer is constant.
