Acoustic matching body, ultrasonic probe, and ultrasonic measuring device

Abstract

An acoustic matching body includes a convex curved surface formed by generatrices that extend parallel to one another and a groove formed on the curved surface along a line of intersection between a plane intersecting the generatrices and the curved surface.

Description

technical field [0001] The invention relates to an acoustic matching body, an ultrasonic probe, an ultrasonic measuring device and the like. Background technique [0002] As a specific example of an ultrasonic measurement device, an ultrasonic diagnostic device is generally known. Ultrasonic diagnostic devices are used, for example, to form images of tissues in the body. The ultrasound probe is pressed against the body surface while the image is being formed. At this time, an acoustic coupling material called water is filled between the ultrasonic probe and the body surface instead of air. The acoustic coupling material plays the role of matching the acoustic impedance of the ultrasonic probe with that of the human body. In this way, ultrasonic waves can be efficiently transmitted between the ultrasonic probe and the body surface according to the action of the acoustic coupling material. [0003] In Patent Document 1, the front end surface of the ultrasonic probe, that i...

Problems solved by technology

However, when the emitting surface is pressed against the body surface, there is a possibility that the slight unevenness may be blocked by the body surface due to adaptation to the body surface.

If the launch surface moves relative to the body surface, water will not be adequately replenished between the launch surface and the body surface

Also, when the emitting surface is not circular with the water supply port as the center, it causes water to escape from the contour near the water supply port, so that the water cannot spread far from the water supply port
