摘要：
The present disclosure provides a beamforming apparatus, ultrasonic probe having the same, ultrasonic diagnostic apparatus, and controlling method thereof, which increases the quality of an image in a region of interest by adjusting time delays of analog and digital beamformers in a two dimensional (2D) transducer of the ultrasonic diagnostic apparatus.In accordance with an aspect of the present disclosure, a beamforming apparatus for beamforming ultrasound received through a two dimensional (2D) arrayed ultrasonic transducer is provided. The apparatus includes an analog beamformer for delaying analog signals received from a subarray including at least one array of the transducer； an analog-to-digital converter (ADC) for converting an analog signal to a digital signal； a digital beamformer for beamforming the digital signal； and a beamformer controller for calculating an initial time delay based on a reference focus point corresponding to a region of interest, and determining a starting point of a sample and hold (S/H) circuit included in the analog beamformer.
