Abstract:
An ultrasound diagnostic apparatus comprising:a probe outputting RF signals; N phase detectors for converting the RF signals outputted from the probe into baseband signals In and Qn, where â€œNâ€  denotes a first predetermined natural number and â€œnâ€  denotes a second predetermined natural number set as 2&lE;n&lE;N; and a reception beam former for processing the baseband signals In and Qn into a time-division-multiplexed signal; wherein the reception beam former comprises means for multiplying the baseband signals In and Qn by phase shift data to generate multiplication-resultant signals, means for delaying the multiplication-resultant signals to generate delay-resultant signals; and means for combining the delay-resultant signals into the time-division-multiplexed signal.
