Which process occurs when the transducer receives a returned echo and converts it into an electrical signal?

• A. Transmission
• B. Damping
• C. Reception
• D. Reflection

Answer: (C)

The key idea is what the transducer does when an echo returns. After the ultrasound pulse travels into the body and some energy is reflected back from boundaries, the transducer switches from sending to receiving. It converts that returning mechanical energy of the echo into an electrical signal that the system can process and display. That conversion during the receiving phase is known as reception. Transmission is the act of emitting the ultrasound pulse. Reflection describes the boundary process that sends echoes back toward the transducer. Damping relates to shaping and controlling the transducer’s signal to reduce ringing. So the step that literally turns the incoming echo into an electrical signal is reception.
