摘要

The purpose of the present invention is to provide an ultrasound examination method and an ultrasound examination device capable of simultaneously displaying a plurality of flaws located at different sites in a single still image, while leveraging the advantages and overcoming the weaknesses of conventional back propagation analysis. The ultrasound examination method of the present invention uses ultrasonic waves to locate flaws inside a test specimen, and is characterized by comprising: a step for preparing a model of the test specimen; a step for setting and inputting a measurement condition for the ultrasonic waves; a step for controlling an ultrasonic probe in accordance with the measurement condition to emit incident ultrasonic waves into the test specimen and receive reflected waves of the incident waves; a step for performing a back propagation analysis on the model using waveform signals of the reflected waves, and creating a group of back propagation still images arranged in reverse-chronological order; a step for performing a forward propagation analysis on the model using waveform signals of the incident waves, and creating a group of forward propagation still images arranged in chronological order; and a step for calculating to combine the group of forward propagation still images and the group of back propagation still images to create a single still image showing the locations of the flaws.
