Abstract
An ultrasonic diagnostic apparatus includes an input unit that supplies information indicating an velocity range of interest of a moving body inside a subject body as an input; and a velocity range setting control unit that sets a variable detectable velocity range as a predetermined velocity range based on the information supplied from the input unit. The variable detectable velocity range is a wider velocity range than the velocity range of interest and covering the velocity range of interest. The apparatus also includes an image processing control unit that allocates color scale data to each velocity within the detectable velocity range to generate the velocity image based on the color scale data allocated and a calculated velocity.
Claims9
An ultrasonic diagnostic apparatus transmitting/receiving ultrasound to an interior of a subject body plural times to obtain plural pieces of ultrasound data, generating and outputting an ultrasound tomographic image of the interior of the subject body based on the obtained ultrasound data, calculating a velocity of a moving body that moves in the subject body as a velocity within a predetermined velocity range, and generating and outputting a velocity image that indicates the velocity of the moving body based on the calculated velocity and color scale data, the ultrasonic diagnostic apparatus comprising:
- an input unit that supplies information indicating an velocity range of interest of the moving body as an input;
- a velocity range setting control unit that sets a variable detectable velocity range as the predetermined velocity range based on the information supplied from the input unit, the variable detectable velocity range being a wider velocity range than the velocity range of interest and covering the velocity range of interest;
- and
- an image processing control unit that allocates the color scale data to each velocity within the detectable velocity range to generate the velocity image based on the color scale data allocated and the calculated velocity.
