<p>An ultrasonic diagnostic apparatus according to the present invention is designed to measure a vascular wall. The apparatus includes: a transmitting section that drives a probe to transmit an ultrasonic wave toward a subject including a blood vessel; a receiving section that receives an ultrasonic echo, produced by getting the ultrasonic wave reflected by the subject, at the probe to generate a received signal; a tomographic image processing section for generating an image signal based on the received signal to present the tomographic image of the subject on a display section; a first borderline generating section for determining a first type of borderline based on the tomographic image presented on the display section; and a second borderline generating section for generating at least one borderline of a second type by translating the first type of borderline.</p>
