Abstract

Provided is a method and apparatus for displaying an image showing an object. The method of displaying an image showing an object includes: displaying a model corresponding to the object; receiving a user input for selecting, from the model, a region of interest (ROI) included in the object; and displaying an image showing the ROI based on the user input.

First claim

What is claimed is:

1. A method of displaying an image showing an object, the method comprising:
displaying a model corresponding to the object;
receiving a user input for selecting, from the model, a region of interest (ROI) included in the object; and
displaying an image showing the ROI based on the user input,
wherein the receiving of the user input comprises receiving a user input for selecting two different points in the model, generating a vector based on the received the user input, identifying a cross-section of the object corresponding to the vector, and setting the cross-section of the object as the ROI,
wherein the model is formed by projecting a 3D shape of the object onto a plane.

2. The method of claim 1 , wherein the displaying of the image showing the ROI comprises displaying the image showing the ROI corresponding to a vector between the two different points.

3. The method of claim 1 , wherein the displaying of the image showing the ROI comprises displaying the image showing the ROI corresponding to a normal vector, and
wherein the normal vector comprises a normal vector that is orthogonal to a vector between the two different points.

4. The method of claim 3 , further comprising receiving a user input for changing a position of at least one of the vector between the two different points and the normal vector,
wherein the displaying of the image showing the ROI comprises displaying the image showing the ROI corresponding to the at least one of the vector and the normal vector whose position has been changed.

5. The method of claim 1 , wherein the receiving of the user input comprises receiving a user input for selecting one of a plurality of circles depicted on the model, and
wherein the displaying of the image showing the ROI comprises displaying the image showing the ROI corresponding to the selected circle.

6. The method of claim 1 , wherein the receiving of the user input comprises receiving a user input for selecting a point in the model, and
wherein the displaying of the image showing the ROI comprises displaying the image showing the ROI corresponding to a vector between the selected point and a central point of the model.

7. The method of claim 1 , wherein the receiving of the user input comprises receiving a user input for selecting one of a plurality of segments into which the model is partitioned, and
wherein the displaying of the image showing the ROI comprises displaying the image showing the ROI corresponding to the selected segment.

8. The method of claim 1 , wherein the receiving of the user input comprises receiving a user input for designating an angle corresponding to the ROI.

9. The method of claim 1 , further comprising:
receiving a user input for requesting enlargement or reduction of a shape of the ROI in the displayed image; and
displaying an image showing the ROI whose shape has been enlarged or reduced based on the user input.

10. The method of claim 1 , wherein the object comprises an internal organ, and the model comprises a two-dimensional (2D) image showing the internal organ.

11. The method of claim 1 , wherein the image showing the ROI comprises a 2D image or a three-dimensional (3D) image.

12. A non-transitory computer-readable medium having recorded thereon a program for executing the method of claim 1 on a computer.

13. An apparatus for displaying an image showing an object, the apparatus comprising:
a display configured to display a model corresponding to the object;
an input interface configured to receive a user input for selecting, from the model, a region of interest (ROI) included in the object; and
an image processor configured to generate an image showing the ROI based on the user input,
wherein the display displays the generated image,
wherein the input interface receives a user input for selecting two different points in the model, and
wherein the image processor generates a vector based on the received the user input, identifies a cross-section of the object corresponding to the vector, and sets the cross-section of the object as the ROI,
wherein the model is formed by projecting a 3D shape of the object onto a plane.

14. The apparatus of claim 13 , wherein the image processor generates the image showing the ROI corresponding to a vector between the two different points.

15. The apparatus of claim 13 , wherein the image processor generates the image showing the ROI corresponding to a normal vector, and
wherein the normal vector comprises a normal vector that is orthogonal to a vector between the two different points.

16. The apparatus of claim 15 , wherein the input interface receives a user input for changing a position of at least one of the vector between the two different points and the normal vector, and
wherein the image processor generates the image showing the ROI corresponding to the at least one of the vector and the normal vector whose position has been changed.

17. The apparatus of claim 13 , wherein the input interface receives a user input for selecting one of a plurality of circles depicted on the model, and
wherein the image processor generates the image showing the ROI corresponding to the selected circle.

18. The apparatus of claim 13 , wherein the input interface receives a user input for selecting a point in the model, and
wherein the image processor generates the image showing the ROI corresponding to a vector between the selected point and a central point of the model.

19. The apparatus of claim 13 , wherein the input interface receives a user input for selecting one of a plurality of segments into which the model is partitioned, and
wherein the image processor generates the image showing the ROI corresponding to the selected segment.

20. The apparatus of claim 13 , wherein the input interface receives a user input for designating an angle corresponding to the ROI.

21. The apparatus claim 13 , wherein the input interface receives a user input for requesting enlargement or reduction of a shape of the ROI in the displayed image, and
wherein the image processor generates an image showing the ROI whose shape has been enlarged or reduced based on the user input.

22. The apparatus of claim 13 , wherein the object comprises an internal organ, and the model comprises a two-dimensional (2D) image showing the internal organ.

23. The apparatus of claim 13 , wherein the image showing the ROI comprises a 2D image or a three-dimensional (3D) image.
