ARRANGEMENT TYPE ULTRASONIC PROBE

摘要

PURPOSE: To provide an arrangement type probe by which resolution capacity in a short axial direction is improved and sensitivity and image are made good. CONSTITUTION: This arrangement type ultrasonic probe which is composed by arrangement of plural lane-shaped piezoelectric elements 2 in the width direction has such a constitution that an acoustic matching layer 4 of uniform thickness is formed on a surface of a recessed face which is a lengthwise direction of the piezoelectric element 2, and a filler 8 which has a smaller sound velocity than a living body is burried-provided on the surface of the acoustic matching layer 4 to make the arrangement type probe be a flat face.
