Title:
ACOUSTIC COUPLER, ULTRASONIC IMAGE PROCESSING METHOD AND ULTRASONIC IMAGING DEVICE
Document Type and Number:
Japanese Patent JP2022172695
Kind Code:
A
Abstract:
To provide an acoustic coupler for ultrasonic imaging which can detect the attitude of an ultrasonic probe from an image.SOLUTION: An acoustic coupler 10 comprises: a first layer 11 which contacts with an ultrasonic probe of an ultrasonic imaging device; a second layer 12 which contacts with an imaging object; and an intermediate layer 13 which is between the first layer and the second layer and made of a material with the high elastic modulus. The intermediate layer 13 includes a plurality of markers made of a material reflecting the ultrasonic wave in the vicinity of a boundary of, for example, adjacent two layers at different positions in the travel direction of the ultrasonic wave. The ultrasonic imaging device detects the attitude of the ultrasonic probe from the image of the markers included in the ultrasonic image.SELECTED DRAWING: Figure 1
