Abstract

Provided is a three-dimensional (3D) ultrasound system and a 3D ultrasound system operating method that may obtain 3D ultrasound data with respect to an object inside a human body to determine an accurate sagittal view. The 3D ultrasound system may include a scanner to generate ultrasound data including image data generated by scanning an object inside a human body, a processing unit to detect a center point of the object from the generated ultrasound data, and to generate, on the ultrasound data, a virtual plane on which the detected center point is placed, and a controller to rotate the ultrasound data based on the image data included in the virtual plane and to determine a sagittal view with respect to the object.

First claim

What is claimed is:

1. An ultrasound system, the system comprising:
a scanner configured for scanning a human body to obtain three-dimensional (3D) ultrasound data including data for a plurality of reference images, each of which illustrating a side of a fetus; and
a controller configured to determine, as a mid-sagittal view image, a particular reference image from among the plurality of reference images by rotating the 3D ultrasound data so that a falx region included in the particular reference image is brighter than a falx region included in an adjacent reference image which is adjacent to the particular reference image from among the plurality to reference images.

2. The system of claim 1 , wherein the controller is further configured to rotate the 3D ultrasound data so that the particular reference image including the falx region with the highest brightness is to be identified.

3. The system of claim 1 , wherein the controller is further configured to perform:
determining, from the 3D ultrasound data, a first feature point associated with a dorsum nasi of the fetus;
determining, based on the first feature point, a second feature point associated with a palate of the fetus; and
setting a center point of an object based on the determined second feature point.

4. The system of claim 1 , wherein, when the object is the fetus, the system further comprises:
a measuring unit configured to measure a thickness of a NT (Nuchal Translucency) based on the determined mid-sagittal view.

5. The system of claim 1 , wherein, when the object is the fetus, the system further comprises:
a measuring unit configured to measure an angle between a first feature point associated with a dorsum nasi of the fetus and a second feature point associated with a palate of the fetus based on the determined mid-sagittal view image.

6. The system of claim 1 , wherein the rotation of the 3D ultrasound data is performed automatically or according to a manipulation of an operator.

7. The system of claim 1 , wherein the controller is further configured to finely rotate the 3D ultrasound data based on a manipulation of an operator to redetermine the mid-sagittal view.

8. A method of operating a 3D ultrasound system, the method comprising:
scanning a human body to obtain three-dimensional (3D) ultrasound data including data for a plurality of reference images, each of which illustrating a side of a fetus; and
determining via a controller, as a mid-sagittal view image, a particular reference image from among the plurality of reference images by rotating the 3D ultrasound data so that a falx region included in the particular reference image is brighter than a falx region included in an adjacent reference image which is adjacent to the particular reference image from among the plurality to reference images.

9. The method of claim 8 , further comprising:
rotating the 3D ultrasound data so that the particular reference image including the falx region with highest brightness is to be identified.

10. The method of claim 8 , further comprising:
determining, from the 3D ultrasound data, a first feature point associated with a dorsum nasi of the fetus;
determining, based on the first feature point, a second feature point associated with a palate of the fetus; and
setting a center point of an object based on the determined second feature point.

11. The method of claim 8 , further comprising:
measuring a thickness of a NT (Nuchal Translucency) based on the determined mid-sagittal view.

12. The method of claim 8 , further comprising:
measuring an angle between a first feature point associated with a dorsum nasi of the fetus and a second feature point associated with a palate of the fetus based on the determined mid-sagittal view image.

13. The method of claim 8 , wherein the rotation of the 3D ultrasound data is performed automatically or according to a manipulation of an operator.

14. The method of claim 8 , further comprising:
redetermining the mid-sagittal view by finely rotating the 3D ultrasound data based on a manipulation of an operator.
