Abstract

Disclosed herein is an ultrasound imaging apparatus capable of setting a region of interest having a shape corresponding to a shape of the cervix canal in an elasticity image of the cervix and displaying the region of interest, and a control method thereof. The ultrasound imaging apparatus includes a display unit configured to display an ultrasound elasticity image and a controller configured to select a point included in a path corresponding to the cervix canal in the elasticity image of the cervix displayed on the display unit, configured to set a region of interest having a shape corresponding to a shape of at least one portion of the cervix canal based on the selected point, and configured to display the region of interest on the display unit.

First claim

1 . An ultrasound imaging apparatus comprising:
a display unit configured to display an ultrasound elasticity image; and a controller configured to select a point included in a path corresponding to the cervix canal in the ultrasound elasticity image of the cervix displayed on the display unit, configured to set a region of interest having a shape corresponding to a shape of at least one portion of the cervix canal based on the selected point and configured to display the region of interest on the display unit.

2 . The ultrasound imaging apparatus of claim 1 wherein
the point included in the path comprises at least one of an external orifice of the uterus, an internal orifice of the uterus, and a feature point in the cervix canal.

3 . The ultrasound imaging apparatus of claim 2 wherein
the feature point comprises a point corresponding to a curved portion of the cervix.

4 . The ultrasound imaging apparatus of claim 1 wherein
the controller sets a region of interest including a boundary having a shape corresponding to the path and being spaced apart with respect to the path corresponding to the cervix canal with a predetermined distance in directions that are opposite to each other.

5 . The ultrasound imaging apparatus of claim 1 wherein
the display unit displays a region of interest including a boundary having a shape corresponding to the path and being spaced apart with respect to the path corresponding to the cervix canal with a predetermined distance in directions that are opposite to each other

6 . The ultrasound imaging apparatus of claim 1 wherein
the controller calculates elasticity information including a ratio of an elasticity value of a first region including the cervix canal in the region of interest and an elasticity value of a second region that is outside of the first region.

7 . The ultrasound imaging apparatus of claim 6 wherein
the controller calculates an elasticity value of a first region including the cervix canal in the region of interest

8 . The ultrasound imaging apparatus of claim 1 wherein
the controller calculates an elasticity value of the external orifice of the uterus, an elasticity value of the internal orifice of the uterus, and a ratio of the elasticity value of the external orifice of the uterus and the elasticity value of the internal orifice of the uterus.

9 . The ultrasound imaging apparatus of claim 1 further comprising:
an input unit configured to receive an input of a command to select a point included in a path corresponding to the cervix canal in the elasticity image of the cervix displayed on the display unit.

10 . A control method of an ultrasound imaging apparatus comprising:
receiving an input of a command to select a point included in a path corresponding to the cervix canal in an elasticity image of the cervix displayed on a display unit; setting a region of interest having a shape corresponding to a shape of the cervix canal when a point included in a path corresponding to the cervix canal is selected; and displaying the set region of interest on the display unit.

11 . The control method of claim 10 wherein
the set of the region of interest comprises setting a region of interest including a boundary having a shape corresponding to the path and being spaced apart with respect to the path corresponding to the cervix canal with a predetermined distance in directions that are opposite to each other.

12 . The control method of claim 10 wherein
the display of the region of interest on the display unit comprises displaying a region of interest including a boundary having a shape corresponding to the path and being spaced apart with respect to the path corresponding to the cervix canal with a predetermined distance in directions that are opposite to each other.

13 . The control method of claim 10 further comprising:
calculating elasticity information including a ratio of an elasticity value of a first region including the cervix canal in the region of interest and an elasticity value of a second region that is outside of the first region.

14 . The control method of claim 10 further comprising:
calculating an elasticity value of a first region including the cervix canal in the region of interest.

15 . The control method of claim 10 further comprising:
calculating an elasticity value of the external orifice of the uterus, an elasticity value of the internal orifice of the uterus, a ratio of the elasticity value of the external orifice of the uterus and the elasticity value of the internal orifice of the uterus, and a ratio of certain elasticity value distribution region included in the region of interest.
