Which handheld device in an ultrasound system both sends and receives the ultrasound signals?

Explanation:
In ultrasound imaging, the same element converts electrical energy into sound waves and then converts the returning echoes back into electrical signals. That dual function is what makes the transducer the handheld device that sends and receives ultrasound signals. It’s typically housed as the probe you hold against the body, because it contains the piezoelectric crystals that generate and detect the echoes. A receiver on its own would only process signals after they arrive; a sensor isn’t the standard term for the active send–receive element in this context.
