THREE-DIMENSIONAL ULTRASONIC IMAGING APPARATUS

The object of the present invention is to provide a the three-dimensional ultrasonic imaging apparatus (10) for improving accuracy of internal inspection of an object (14) to be inspected and enabling an automatic determination by means of ultrasonic waves. The three-dimensional ultrasonic imaging apparatus (10) according to the present invention includes: an ultrasonic transducer (11) having a plurality of piezoelectric vibrators (22); a driving element selecting portion (13) for selecting a piezoelectric vibrator (22) to emit an ultrasonic wave among a plurality of the piezoelectric vibrators (22); a signal detecting circuit (16) for causing ultrasonic waves emitted by the selected piezoelectric vibrator (22) to enter the object (14) to be inspected, receiving echo reflected from the object (14) to be inspected, and thereby detecting an electric signal corresponding to the reflected echo; a signal processing portion (17) for generating three-dimensional imaging data by subjecting the electric signal corresponding to the detected reflected echo to parallel arithmetic processing; and a display processing device (18) for receiving the three-dimensional imaging data from the signal processing portion, correcting image luminance of the three-dimensional imaging data so as to flatten imaging intensity distribution in the plane direction of the surface of the object (14) to be inspected, and then displaying a corrected result.
