1. An ultrasonic diagnostic apparatus comprising:

  • an ultrasonic probe driving section for driving an ultrasonic probe for transmitting an ultrasonic transmission wave to an object to be measured including a blood vessel in which fluid moves and a fluid portion within the blood vessel, the fluid portion being an area;

    a receiving section for amplifying an ultrasonic reflected wave obtained when the ultrasonic transmission wave reflects from the object to be measured and is received by the ultrasonic probe;

    a phase detecting section for phase-detecting the ultrasonic reflected wave;

    a computing section for obtaining the velocities of the object to be measured at a plurality of measuring positions of the object to be measured from the phase-detected signal and obtaining the deformation amounts and/or elastic moduli in at least one micro-region from the velocities and in a radial direction of the blood vessel, the micro-region defined by a portion of the object to be measured between at least two of the measuring positions;

    a fluid determining section for determining the fluid portion in the object to be measured in accordance with the phase-detected signal; and

    an image data generating section for generating image data for two-dimensionally image-displaying the deformation amounts and/or elastic moduli of the object to be measured in a region other than the fluid portion by using the information determined by the fluid determining section.
