The electronics within the ultrasound system that create spike patterns is called the _______.

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

Answer: (B)

Beamforming is the process of shaping the ultrasound beam by coordinating the timing and amplitude of the electrical pulses sent to each element in the transducer array. The spike patterns come from these coordinated excitations: by applying precise delays and varying drive signals across elements, the waves combine constructively in a specific direction to form a focused, steerable beam. The electronics that generate and manage these patterns—the beam former—sit between the pulser (transmitter) and the transducer and control how each element is driven. The transmitter would simply send a pulse without the channel-by-channel timing adjustments needed for focusing, and the receiver is involved with processing echoes after transmission, not with creating the initial spike pattern.
