Ultrasonic diagnostic apparatus and ultrasonic diagnostic apparatus control method
First Claim
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.

10. A control method of an ultrasonic diagnostic apparatus having a transmitting/receiving section for transmitting/receiving an ultrasonic wave, a phase-detecting section for phase-detecting the received ultrasonic wave, and a computing section for computing a deformation amount and/or elastic modulus in accordance with the phase-detected ultrasonic wave, comprising the steps of:
-
(A) transmitting an ultrasonic 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, and receiving an ultrasonic reflected wave obtained when the ultrasonic wave reflects from the object to be measured; (B) phase-detecting the ultrasonic reflected wave; (C) obtaining the velocities of the object to be measured at a plurality of measuring positions of the object to be measured in accordance with 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; (D) determining the fluid portion in the object to be measured in accordance with the phase-detected signal; and (E) generating image data for two-dimensionally image-displaying the deformation amount and/or elastic modulus of the object to be measured in a region other than the fluid portion by using information of the fluid portion determined in step (D). - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
