(EN) Ultrasonic probe and ultrasonic diagnostic device
要約
(EN)

An ultrasonic probe (102) which has high propagation efficiency of ultrasound and can obtain a high resolution ultrasonic diagnostic image. The ultrasonic probe (102) includes an ultrasonic transducer including: a piezoelectric body (208) which generates ultrasound; and a first matching layer (101) which is disposed in a predetermined direction as seen from the piezoelectric body (208) and is for performing acoustic matching between the piezoelectric body (208) and a subject. The first matching layer (101) includes a plurality of matching regions (101a, 101b, 101c) which have a uniform thickness in the predetermined direction, are arranged in a direction perpendicular to the predetermined direction, and include at least two matching regions having frequency characteristics of ultrasound transmittance that are different from each other.
