ULTRASOUND DIAGNOSTIC APPARATUS AND METHOD FOR DETECTING DETERIORATION OF ULTRASOUND PROBE TRANSDUCER

摘要

In order to provide an ultrasound diagnostic apparatus and method for detecting deterioration of a transducer of an ultrasound probe in which or by which deterioration of a transducer of an ultrasound probe can be correctly detected, an ultrasound diagnostic apparatus comprising an ultrasound probe 12 for transmitting and receiving ultrasonic waves, and a tomographic image constructing part 22 for constructing a tomographic image from reflected echo signals received with the ultrasound probe 12 is provided with a brightness analyzing part 30 for analyzing brightness of a plurality of regions of interest in the tomographic image, and a judging part 34 for judging whether a transducer of the ultrasound probe has deteriorated or not on the basis of analyzed brightness.
