An ultrasonic diagnostic apparatus according to a present embodiment includes transceiver circuitry, image generating circuitry and processing circuitry. The transceiver circuitry is configured to transmit, to an ultrasonic probe, a transmission signal for transmitting ultrasonic waves, and to receive a received signal based on the ultrasonic waves. The image generating circuitry is configured to generate an ultrasonic image where temporal variation over a given time period is imaged, based on the received signal, and to display the ultrasonic image to a display. The processing circuitry is configured to: (A) set a measurement range on the ultrasonic image； (B) generate a marker for dividing the measurement range, at substantially equal intervals, the number of the marker according to the numerically number of beats； and (C) superimpose the marker on the displayed ultrasonic image.
