Probe for ultrasonic diagnostic apparatus and method of manufacturing the same

摘要

A probe for an ultrasonic diagnostic apparatus includes a case, a piezoelectric member provided inside the case, at least one acoustic matching layer disposed at a front of the piezoelectric member, an acoustic lens disposed at a front of the acoustic matching layer, and a backing member disposed at a rear of the piezoelectric member and provided with a plurality of pores to reduce sound waves transmitted to the rear of the piezoelectric member and to allow to adjust an acoustic impedance. A method of manufacturing the probe for an ultrasonic diagnostic apparatus includes the operations of preparing a fluid to form a backing layer, pouring the fluid into a mold, hardening the fluid and removing the mold.
