Method and apparatus for displaying medical image

1. A method performed by a medical image display apparatus, the method comprising:

generating a three-dimensional (3D) stereoscopic image from volume data of an object, by an image generator of the medical image display apparatus, wherein the volume data of the object is acquired by a data acquisitor of the medical image display apparatus;

generating at least one 2D stereoscopic image, by the image generator, based on at least one of a direction, a gradient, and a depth of a plane where a cross section of the object is located in the 3D stereoscopic image, wherein the at least one 2D stereoscopic image is parallel to or has a same depth as the plane; and

displaying a medical image including the 3D stereoscopic image and the at least one 2D stereoscopic image in a stereoscopic imaging method, on a display screen of the medical image display apparatus,

wherein the generating the 3D stereoscopic image comprises:

performing a rendering of the volume data of the object at a point of view of one virtual camera of the medical image display apparatus;

generating a plurality of images by dividing the rendered volume data of the object; and

rendering a plurality of 3D stereoscopic images by setting the virtual camera in a virtual space where the object is located and changing a direction of ray casting towards the object from the virtual camera.

2. The method of claim 1 , wherein the at least one 2D stereoscopic image indicates at least one cross section of the object.

3. The method of claim 1 , further comprising receiving a user's input by a receiver of the medical image display apparatus; and

generating a non-stereoscopic image corresponding to the 3D stereoscopic image and the at least one 2D stereoscopic image,

wherein the displaying of the medical image comprises displaying a stereoscopic image instead of a non-stereoscopic image which is being displayed, or displaying a non-stereoscopic image instead of a stereoscopic image which is being displayed, based on the user's input.

4. The method of claim 1 , further comprising generating a medical image including a non-stereoscopic image of the object.

5. The method of claim 1 , wherein the displaying of the medical image comprises determining a type and the number of images to be displayed according to a user's input.

6. The method of claim 5 , wherein the generating of the 3D stereoscopic image comprises generating a plurality of 3D stereoscopic images in which at least one of a direction, a gradient, and a depth of the object shown in the plurality of 3D stereoscopic images is different, and

the displaying of the medical image comprises displaying at least one of the plurality of 3D stereoscopic images based on the user's input.

7. The method of claim 1 , wherein the at least one 2D stereoscopic image includes a stereoscopic image of a cross section of the object, which is selected based on a user's input from the 3D stereoscopic image.

8. The method of claim 1 , wherein the at least one 2D stereoscopic image includes stereoscopic images of three cross sections of the object, which are orthogonal to each other.

9. The method of claim 1 , wherein the at least one 2D stereoscopic image includes a stereoscopic image of a curve-shaped cross section of the object.

10. An apparatus configured to display a medical image of an object, the apparatus comprising:

a data acquisitor configured to acquire volume data of the object;

an image generator configured to generate a three-dimensional (3D) stereoscopic image from the volume data of the object and at least one 2D stereoscopic image generated based on at least one of a direction, a gradient, and a depth of a plane where a cross section of the object is located in the 3D stereoscopic image, wherein the at least one 2D stereoscopic image is parallel to or has a same depth as the plane; and

a display screen configured to display the medical image including the 3D stereoscopic image and the at least one 2D stereoscopic image in a stereoscopic imaging method,

wherein the image generator renders the 3D stereoscopic image by:

performing a rendering of the volume data of the object at a point of view of one virtual camera of the medical image display apparatus;

generating a plurality of images by dividing the rendered volume data of the object; and

rendering a plurality of 3D stereoscopic images by setting the virtual camera in a virtual space where the object is located and changing a direction of ray casting towards the object from the virtual camera.

11. The apparatus of claim 10 , wherein the image generator generates the 2D stereoscopic image based on at least one of a direction, a gradient, and a depth of a plane corresponding to the cross section in the 3D stereoscopic image, and wherein the at least one 2D stereoscopic image indicates at least one cross section of the object.

12. The apparatus of claim 10 , further comprising a receiver configured to receive a user's input,

wherein the image generator further generates a non-stereoscopic image corresponding to the 3D stereoscopic image and the at least one 2D stereoscopic image, and

the display screen displays a stereoscopic image instead of a non-stereoscopic image which is being displayed, or a non-stereoscopic image instead of a stereoscopic image which is being displayed, based on the user's input.

13. The apparatus of claim 10 , wherein the image generator generates the medical image further including a non-stereoscopic image of the object.

14. The apparatus of claim 10 , further comprising a receiver configured to receive a user's input,

wherein the display screen determines a type and the number of images to be displayed according to a user's input.

15. The apparatus of claim 14 , wherein the image generator generates a plurality of 3D stereoscopic images in which at least one of a direction, a gradient, and a depth of the object shown in the plurality of 3D stereoscopic images is different, and
