Abstract: The present invention relates to an imaging method for a damaged pipe to take an image of a damaged part of a pipe. To achieve this, the imaging method for a damaged pipe comprises a step of mounting a piezoelectric element on a pipe; a step of generating ultrasonic waves in the piezoelectric element; a step of measuring an ultrasonic signal reflected by the damaged part of the pipe using the piezoelectric element; and a step of offsetting the dispersion of the ultrasonic signal measured by the piezoelectric element and recovering the waveform using an image processing part connected to the piezoelectric element.
