Abstract
An ultrasonic diagnostic apparatus includes a transmitting section that generates a drive signal to drive a probe in order to transmit an ultrasonic wave toward a subject to be deformed periodically under stress. A receiving section receives an echo, produced when the ultrasonic wave is reflected from the subject, at the probe to generate a received echo signal. A computing section determines a thickness change waveform, representing a variation in distance between two arbitrary measuring points on the subject, based on the received echo signal. A reference waveform generating section outputs a reference waveform. The apparatus obtains a subject's internal information by comparing the thickness change waveform and the reference waveform to each other.
