Which component converts electric energy into mechanical vibrations (sound energy) for transmission into the patient?

Which component converts electric energy into mechanical vibrations (sound energy) for transmission into the patient?

• A. Transducer
• B. Memory
• C. Receiver
• D. Scan converter

Answer: (A)

The essential idea is that the device that turns electrical energy into sound energy to send into the body is the transducer. It uses piezoelectric crystals that vibrate when driven by an electrical signal, producing ultrasound waves that travel into tissues. This emission is what allows the ultrasound to probe inside the body. Other components have different roles: memory stores image data, the receiver handles the electrical signals from echoes, and the scan converter formats data for display. Since the question asks which part generates the ultrasound energy for transmission, the transducer is the correct choice.
