ULTRASONIC PROBE, CONNECTION COMPONENT FOR ARRAY ELEMENTS AND ULTRASONIC IMAGING SYSTEM THEREOF

摘要

A connection component for array elements in an ultrasonic probe comprises a first-layer body and a second-layer body, wherein the second-layer body is connected with the first-layer body, and an area of the second-layer body is smaller than an area of the first-layer body. A region in the first-layer body that extends beyond the second-layer body is provided with at least one first-layer conductive element penetrating through the first-layer body. A lower surface of the second-layer body is provided with at least one second-layer conductive element penetrating through the second-layer body and the first-layer body. A signal transmission line is connected to the array elements by the first-layer conductive elements and the second-layer conductive elements. The connection component for array elements is in a stepped shape. The signal transmission line is connected to an array element assembly through the stepped connection component for array elements to provide sufficient space.
