Which system component is affected when you adjust the output power control?

• A. Pulser
• B. Memory
• C. Scan converter
• D. Beam former

Answer: (A)

The main concept is that output power control directly changes the energy of the transmitted pulse by altering the electrical drive sent to the transducer. This drive is produced by the pulser, so adjusting the output power changes the pulser’s output and thus the acoustic power emitted. The other components aren’t responsible for setting how much power is transmitted: memory stores data, the scan converter handles image formatting, and the beam former manages timing and per-element signal shaping for focusing, not the overall transmit power.
