PROBE AND MANUFACTURING METHOD THEREOF

摘要

Disclosed herein is a probe including: an acoustic module including a piezoelectric layer configured to generate ultrasonic waves, a matching layer configured to reduce a difference in acoustic impedance between the piezoelectric layer and an object, and a backing layer configured to absorb ultrasonic waves generated by the piezoelectric layer and transmitted backward from the piezoelectric layer; a plurality of attenuation layers provided at both edges of the upper surface of the acoustic module, and configured to attenuate ultrasonic waves generated by the acoustic module; and a lens layer disposed to cover the upper surfaces of the attenuation layers, and configured to focus ultrasonic waves transmitted forward from the piezoelectric layer at a predetermined point.
