Abstract
An apparatus and a method for ultrasonic testing obtains high-resolution and high-S/N ratio testing results by driving a number of piezoelectric elements using fewer pulsers and receivers in comparison with the number of elements composing an array transducer. A sensor information setter sets a plurality of piezoelectric element groups used for transmission and a plurality of piezoelectric element groups used for reception among the plurality of piezoelectric elements composing an ultrasonic array transducer. A computer transmits an ultrasonic wave from the element cluster set for transmission, and stores an ultrasonic wave received by the element cluster set for reception. The procedure is repeated including different element cluster sets for transmission and reception to obtain first receive signals. The first receive signals are summed to obtain a second receive signal; and the second receive signal is displayed with reference to the sensor center position on a display unit.
