Which component is primarily responsible for dynamic aperture in beamforming?

• A. Transducer
• B. Beam former
• C. Processor
• D. Display

Answer: (B)

Dynamic aperture means changing how many receive elements are actively used as depth changes to optimize resolution and signal strength. This control is built into the beamformer, which applies time delays and weighting (apodization) to each element and decides how many elements participate for the receive beam at each depth. By adjusting the active aperture in real time, the beamformer shapes the beam and preserves image quality. The transducer is the physical array that provides the signals, but it doesn’t independently alter the aperture. The processor handles additional signal processing after beamforming, and the display shows the final image. So the beamformer is the component that primarily handles dynamic aperture.
