transÂ·duÂ·cer. A device that converts energy from one form to another. transducer (tranzdooÂ´sur), n a device that is activated by power from one system and then supplies a different form of power to a second system; used to convert electric energy into mechanical energy in ultrasonic and sonic scalers.
Ultrasound is an imaging modality that utilizes high-frequency sound waves to provide cross-sectional images of the body. The ultrasound machine has the following components: monitor, keyboard, processor, data storage and probe or transducer. A transducer performs two functions: it emits sound waves (echoes) at a certain frequency and captures the returning echoes at frequencies dependent on the tissues through which the waves traverse. The sound wave that is returned to the transducer is digitized to appear as echoes or dots on the screen.
