摘要： An ultrasonic probe (11) is constituted by a group of ultrasonic transducer elements arranged in at least one direction. A beam forming unit (91) forms acoustic field sensitivity modulated in a direction substantially orthogonal to a group of scan lines in a subject by focusing an ultrasonic wave on a sequence of sampling points existing along the group of scan lines, and applying delay and apodization on a transmission/reception signal of each of the ultrasonic transducer elements. A detecting unit (90) detects displacements at each of the sampling points in a direction tangential to the group of scan lines and in a direction tangential to a group of curves substantially orthogonal to the scan lines by arithmetic between reception signals for the sampling point at different time points. The group of curves substantially orthogonal to the group of scan lines is a group of curves in the subject, each of the curves being constituted by a sequence of points for which a total of times taken for ultrasonic pulses to reach from two points fixed to the ultrasonic probe (11) is substantially the same.

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.
