According to one embodiment, an ultrasonic diagnostic apparatus comprises a data acquisition unit, an image generation unit, a calculation unit, a determination unit and a measurement unit. The data acquisition unit acquires a plurality of ultrasonic data. The image generation unit generates a plurality of ultrasonic images by using the plurality of ultrasonic data. The calculation unit calculates a feature amount for determining a shift between the two-dimensional section and a central axis of a target blood vessel. The determination unit determines an optimal image from the plurality of ultrasonic images based on the feature amount. The measurement unit measures an intima-media thickness of the target blood vessel by using the optimal image.
