Dynamic receive focusing is not controlled by the sonographer.

• A. True
• B. False
• C. Sometimes
• D. Not applicable

Answer: (A)

Dynamic receive focusing is a beamforming technique where the ultrasound system automatically adjusts the receive focal point as echoes return from different depths. This keeps the beam narrow and improves lateral resolution across the image without requiring manual changes from the operator at each depth. Because this adjustment is built into the system’s electronics and beamformer, the sonographer does not control it in real time. The operator typically influences imaging through settings like depth, gain, and the use of focal zones, but the dynamic receive focusing itself is managed by the machine to optimize focus automatically as echoes propagate. In some systems, there may be a way to enable or disable DRF or choose presets that affect how it operates, but the basic function—adjusting receive focus with depth—remains an automatic process controlled by the equipment, not the user.
