An ultrasonic diagnostic apparatus transmits ultrasound to an interior of a subject body and receives the ultrasound from the interior of the subject body to obtain plural pieces of ultrasound data, calculates a velocity of a moving body in the subject body as a velocity within a predetermined velocity range based on the plural pieces of ultrasound data, and generates and outputs a velocity image which indicates the calculated velocity as a velocity image of the moving body. The ultrasonic diagnostic apparatus includes an input unit which supplies information indicating a velocity range of interest of the moving body as an input, a velocity range setting control unit, and an image processing control unit. The velocity range setting control unit sets a variable detectable velocity range which is wider than the velocity range of interest and which covers the velocity range of interest as the predetermined velocity range based on the information supplied from the input unit. The image processing control unit allocates color scale data to each velocity within the detectable velocity range, and generates the velocity image based on the allocated color scale data and the calculated velocity. |
