FAILURE DIAGNOSIS SYSTEM OF ULTRASONIC ENDOSCOPE APPARATUS, FAILURE DIAGNOSIS METHOD OF ULTRASONIC ENDOSCOPE APPARATUS, AND FAILURE DIAGNOSIS PROGRAM OF ULTRASONIC ENDOSCOPE APPARATUS
Provided are a failure diagnosis system of an ultrasonic endoscope apparatus, a failure diagnosis method of the ultrasonic endoscope apparatus, and a non-transitory computer readable recording medium storing a failure diagnosis program of the ultrasonic endoscope apparatus capable of performing failure diagnosis of the ultrasonic endoscope apparatus with high accuracy. The system controller acquires a reception signal of an ultrasonic vibrator in a state where ultrasonic waves are not transmitted from the ultrasonic vibrator of an ultrasonic endoscope, and performs failure diagnosis of an ultrasonic endoscope apparatus including the ultrasonic endoscope on the basis of the reception signal.
