ULTRASOUND DIAGNOSTIC APPARATUS, METHOD OF TRANSMITTING AND RECEIVING ULTRASONIC WAVE, AND PROGRAM FOR TRANSMITTING AND RECEIVING ULTRASONIC WAVE

摘要

An ultrasound diagnostic apparatus includes plural ultrasound transducers which perform transmission and reception of ultrasonic waves toward a target site of a subject containing a puncture needle. A method of transmitting and receiving an ultrasonic wave uses the ultrasound transducers. The apparatus and the method form an ultrasonic beam to be transmitted from a transmit aperture set on the ultrasound transducers, acquire information relating to a specular-reflective component of the ultrasonic beam in the puncture needle, set a first receive aperture different from the transmit aperture set on the ultrasound transducers on the basis of the information relating to the specular-reflective component of the ultrasonic beam, and process an ultrasonic echo signal received by the ultrasound transducers using the first receive aperture.
