What is the name of the electronics that generate spike patterns in ultrasound systems?

• A. Processor
• B. Beam Former
• C. Transmitter
• D. Receiver

Answer: (B)

Beamforming is the process of shaping and steering the ultrasound beam by coordinating the timing and amplitude of signals sent to each element of the transducer array. The electronics that generate the spike patterns across the array—the precise sequence of pulses sent to every element—are the beamformer. By applying specific time delays (and amplitudes) to each element, the waves combine constructively in the desired direction and depth, creating a focused, steerable beam. This patterning is what makes it possible to scan in different directions without moving the transducer. The transmitter provides the drive signals to the elements, and the receiver handles echoes, but the coordinated spike timing that forms the beam comes from the beamformer.
