Which parameter controls the amplitude of the transmitted beam and the amplitude of the received echoes, ranging from 0 to 500 volts?

• A. Power output
• B. Gain
• C. Dynamic range
• D. Frame rate

Answer: (A)

Power output controls how strong the electrical drive to the transducer is, setting the amplitude of the transmitted ultrasound pulse. A stronger pulse sends more energy into the tissue, which in turn produces echoes with greater amplitude when they return. This same parameter also influences the overall strength of the echoes that are detected, before any gain is applied. By contrast, gain only boosts or attenuates the already received signals after detection, dynamic range defines the span of displayable echo amplitudes, and frame rate affects how quickly images are produced. So the parameter that links both transmitted beam amplitude and received echo amplitude is power output.
