Which system component implements time gain compensation adjustments?

Which system component implements time gain compensation adjustments?

• A. Pulser
• B. Monitor
• C. Receiver
• D. Scan converter

Answer: (C)

Time gain compensation is a depth-dependent amplification applied to echoes as they are received, to offset greater attenuation from deeper tissues. This gain control is implemented by the receiver, which adjusts the signal strength with time (depth) before the data are processed into an image. The pulser only generates the initial ultrasound pulse, the scan converter stores and converts data for display, and the monitor shows the image. So the receiver is the component that implements time gain compensation.
