Knowledge Point

What is an ultrasound transducer and what does it do?

An ultrasound transducer, also called a probe, is a device that produces sound waves that bounce off body tissues and make echoes.

The transducer also receives the echoes and sends them to a computer that uses them to create an image called sonogram.

Moreover, the essential element of each ultrasound transducer is a piezoelectric crystal. It serves to generate as well as receive ultrasound waves.

Mechanical probe

A motor drives a rotating head whose shaft is located at the focal point of the probe surface to rotate in one direction. Two focusing transducers are embedded in the rotating head. When the transducer rotates to face the reflector, it emits ultrasonic pulses. After parabolic launching, a row of parallel linear scanning beams are formed, realizing mechanical scanning. Its advantages are that the sector-shaped mechanical scanning probe has a large field of view for far-area exploration, a small contact area for acoustic coupling with the human body, and the same tangential and lateral resolution. It is suitable for ultrasound examination of heart, small organs, ophthalmology, lumen ducts and abdominal organs.
