Ultrasonic apparatus, control device for ultrasonic apparatus, probe, and peeling detection method

Abstract

An ultra sonic apparatus, a control device for same, a probe, and a peeling detection method are provided; the control device for the ultrasonic apparatus includes: a reference value setting section that sets a reference value based on either the reflectance of an ultrasonic wave reflected from the interface with the air or the reflectance of an ultrasonic wave reflected from the interface with a measurement target; a reference period setting section that sets a reference period ended at the earlier time than the time of receiving an ultrasonic wave that is transmitted from an ultrasonic transducer element and is reflected from the measurement target; and a peeling detecting section that detects peeling of the ultrasonic transducer element by comparing a reception signal, which is output from the ultrasonic transducer element in the reference period, with the reference value.

Description

technical field [0001] The present invention relates to an ultrasonic device, a control device for the ultrasonic device, and the like. Background technique [0002] Patent Document 1 discloses an ultrasonic transducer. On the sensor substrate, in addition to the ultrasonic transducer element group of the transmitting unit and the ultrasonic transducer element group of the receiving unit, an ultrasonic transducer element group for peeling detection is disposed. The sets of ultrasonic transducer elements are covered by a clinging layer. The adherent layer is in close contact with the living body at the time of generation of the ultrasonic image. As a result, the ultrasonic waves output from the transmitter are transmitted from the coherent layer to the living body without passing through the air layer, reflected by organs such as blood vessels and internal organs, and then transmitted from the living body to the coherent layer again.

AI Technical Summary

Problems solved by technology

If the ultrasonic transducer element is not peeled off from the living body, the ultrasonic wave will pass through the surface of the adhesive layer to reach the organs in the living body, so compared with the case where the ultrasonic wave is reflected on the surface of the adhesive layer, the reflected wave will be absorbed by the ultrasonic transducer. Time it takes to receive parts

Accordingly, the processing time increases at the time of determination of peeling
