Which device acts as the clock that instructs the pulser to send an electrical signal and coordinates all system components?

• A. Master synchronizer
• B. Pulser
• C. Beam former
• D. Transducer

Answer: (A)

Timing control coordinates when the pulser fires and when echoes are sampled, keeping every part of the system in sync. The master synchronizer provides that clock signal, telling the pulser when to emit electrical pulses and aligning the timing of other components like the beam former and the data acquisition pipeline. Without this central timing reference, pulses could fire out of phase or data could be acquired at the wrong moments, leading to degraded images. The pulser itself is the device that generates the electrical impulses sent to the transducer to produce ultrasound energy, so it needs a trigger but does not set the overall timing. The beam former shapes the transmitted beam and processes received signals, relying on accurate timing but not serving as the system-wide clock. The transducer is the interface that converts electrical energy to acoustic energy and back, not a timing coordinator.
