Ultrasound Transducers

9 Ultrasound Transducers

Ultrasound transducers consist of arrays of piezoelectric crystals that produce high-frequency sound waves in response to an electrical signal. These crystals interconvert electrical and mechanical energy, allowing for both transmission and reception of sound waves. The piezoelectric element vibrates to produce ultrasound. Piezoelectric crystals change shape under the influence of an electric field. The thickness of the crystal and the propagation speed within determine the frequency. With some transducers, the sonographer can select different crystals within the assembly to produce a different frequency.
