ULTRASONIC APPARATUS, CONTROL DEVICE FOR UNLTRASONIC APPARATUS, PROBE, AND PEELING DETECTION METHOD

摘要

A control device for an 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.

1. A control device for an ultrasonic apparatus, comprising a processor configured to:
set a reference value based on either a reflectance of an ultrasonic wave reflected from an interface with air or a reflectance of an ultrasonic wave reflected from an interface with a measurement target; set a reference period ended at an earlier time than a time of receiving an ultrasonic wave that is transmitted from an ultrasonic transducer element and is reflected from the measurement target; and detect 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.
