ULTRASONIC PROBE AND MANUFACTURING METHOD THEREOF

摘要

An ultrasonic probe including an acoustic module including a transducer layer to generate an ultrasonic wave, a matching layer to reduce an acoustic impedance difference between the transducer layer and a subject, and a backing layer to absorb a ultrasonic wave generated from the transducer layer and proceeding toward a rear, and a plurality of lens layers configured to focus a ultrasonic wave proceeding toward a front of the transducer layer, and each including a different physical property, so that the reception of the ultrasonic wave signal is improved while maintaining wear resistance characteristic and chemical resistance characteristic, as well as the stability with respect to withstanding voltage.
