Which component is used to steer and focus the received ultrasound beams by delaying and summing signals from multiple elements?

• A. Pulser
• B. Beam former
• C. Memory
• D. Display

Answer: (B)

Beamforming is used to steer and focus received ultrasound beams by delaying and summing signals from multiple elements. By applying precise time delays to each element’s signal, echoes from a particular depth or direction line up in time, and when they’re summed, they reinforce each other to form a focused, steerable beam. Changing the pattern of delays across the array lets the system electronically steer the beam and adjust the focal point without moving the probe. The pulser handles the transmitted pulses, memory stores data, and the display presents the image, but the steering and focusing through delayed summation is the job of the beam former.
