Ultrasound diagnostic apparatus |
摘要 |
An ultrasound diagnostic apparatus includes a probe which outputs RF signals. There are N phase detectors for converting the RF signals outputted from the probe into baseband signals In and Qn, where "N" denotes a first predetermined natural number and "n" denotes a second predetermined natural number set as 2<=n<=N. A reception beam former operates for processing the baseband signals In and Qn into a time-division-multiplexed signal. The reception beam former includes a device for multiplying the baseband signals In and Qn by phase shift data to generate multiplication-resultant signals, a device for delaying the multiplication-resultant signals to generate delay-resultant signals, and a device for combining the delay-resultant signals into the time-division-multiplexed signal.
