Apparatus and method for ultrasonic testing |
摘要 |
It is an object of the present invention to provide an apparatus and a method for ultrasonic testing which make it possible to obtain high-resolution and high-S/N ratio testing results through imaging by driving a number of piezoelectric elements, the apparatus and method comprising less number of pulsers and receivers in comparison with the number of elements composing an array transducer. A sensor information setter 102F sets a plurality of piezoelectric element groups (element clusters) used for transmission and a plurality of piezoelectric element groups (element clusters) used for reception out of the plurality of piezoelectric elements composing an ultrasonic array transducer 101. A computer 102G performs the steps of: transmitting an ultrasonic wave from the element cluster set for transmission, and storing an ultrasonic wave received by the element cluster set for reception as a first receive signal; repeating a procedure for changing the element cluster set for transmission and the element cluster set for reception and storing another first receive signal; summing up the plurality of first receive signals obtained by repeating the same procedure to obtain a second receive signal; and displaying the second receive signal with reference to the sensor center position on a display unit 103. |
