Title:
ULTRASOUND IMAGING DEVICE AND METHOD OF GENERATING IMAGE FOR ULTRASOUND IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/183540
Kind Code:
A1
Abstract:
The present invention addresses the problem of imaging a plurality of joining surfaces of a workpiece simultaneously. An ultrasound imaging device (4) which is a means for solving this problem is provided with: a signal processing unit (46) which irradiates ultrasonic waves having a prescribed frequency onto a workpiece (1) by means of a probe (2), subjects reflected ultrasonic waves detected by the probe (2) to a gate process, and outputs displacements of the reflected waves at two joining surfaces of the workpiece (1); an image generating unit (47) which generates images of the two joining surfaces on the basis of the displacements of each reflected wave at the two joining surfaces; and a height adjusting unit (41) which adjusts the height of the probe (2). The height adjusting unit (41) sets the focal point of the probe (2) to be between the two joining surfaces by adjusting the height of the probe (2).
