Medical imaging apparatus and method of displaying medical image

1. A medical imaging apparatus comprising:

a user interface configured to receive an input for setting a region of interest (ROI) in a first medical image and an input for setting first volume rendering properties for the ROI and second volume rendering properties for a remaining region of the first medical image, wherein the remaining region is identified as a region other than the ROI set by a user in the first medical image;

a display; and

one or more processors configured to generate a second medical image by performing volume rendering on the ROI and the remaining region other than the ROI based on the first and second volume rendering properties, respectively, and control the display to display the second medical image,

wherein the one or more processors are further configured to:

display the ROI in the first medical image and at least one item related to the first volume rendering properties via the display, and receive the input for setting the first volume rendering properties via the user interface while displaying the first medical image and the at least one item related to the first volume rendering properties, and

display the remaining region of the first medical image and at least one item related to the second volume rendering properties via the display, and receive the input for setting the second volume rendering properties via the user interface while displaying the second medical image and the at least one item related to the second volume rendering properties.

2. The medical imaging apparatus of claim 1 , wherein the one or more processors perform the volume rendering on the ROI and the remaining region other than the ROI based on the first and second volume rendering properties, respectively, and synthesize a volume rendered medical image of the ROI with a volume rendered medical image of the remaining region other than the ROI, thereby generating the second medical image.

3. The medical imaging apparatus of claim 1 , wherein the second volume rendering properties comprise transparency.

4. The medical imaging apparatus of claim 1 , wherein the second volume rendering properties comprise a color map.

5. The medical imaging apparatus of claim 1 , wherein the second volume rendering properties comprise properties for obtaining a contour of the remaining region.

6. The medical imaging apparatus of claim 1 , wherein at least one of the first and second volume rendering properties is reset.

7. The medical imaging apparatus of claim 1 , wherein the second volume rendering properties comprise at least one selected from the group consisting of a threshold, a gamma curve, a post gain, and an image filter.

8. The medical imaging apparatus of claim 1 , wherein the first volume rendering properties comprise at least one selected from the group consisting of transparency, a color map, a threshold, a gamma curve, a post gain, and an image filter.

9. The medical imaging apparatus of claim 1 , wherein the first and second medical images comprise a three-dimensional (3D) ultrasound image.

10. The medical imaging apparatus of claim 9 , further comprising a probe configured to transmit ultrasound signals to an object and receive ultrasound echo signals reflected from the object,

wherein the one or more processors generate the first medical image based on the received ultrasound echo signals.

11. A method of displaying a medical image, the method comprising:

setting a region of interest (ROI) in a first medical image;

setting first volume rendering properties for the ROI;

setting second volume rendering properties for a remaining region of the first medical image, wherein the remaining region is identified as a region other than the ROI set by a user in the first medical image;

generating a second medical image by performing volume rendering on the ROI and the remaining region other than the ROI based on the first and second volume rendering properties, respectively; and

displaying the second medical image,

wherein the setting of the first volume rendering properties comprises:

displaying the ROI in the first medical image and at least one item related to the first volume rendering properties via the display, and

receiving the input for setting the first volume rendering properties via the user interface while displaying the first medical image and the at least one item related to the first volume rendering properties, and

wherein the setting of the second volume rendering properties comprises:

displaying the remaining region of the first medical image and at least one item related to the second volume rendering properties via the display, and

receiving the input for setting the second volume rendering properties via the user interface while displaying the second medical image and the at least one item related to the second volume rendering properties.

12. The method of claim 11 , wherein in the generating of the second medical image, the second medical image is generated by performing the volume rendering on the ROI and the remaining region other than the ROI based on the first and second volume rendering properties, respectively, and synthesizing a volume rendered medical image of the ROI with a volume rendered medical image of the remaining region other than the ROI.

13. The method of claim 11 , wherein the second volume rendering properties comprise transparency.

14. The method of claim 11 , wherein the second volume rendering properties comprise a color map.

15. The method of claim 11 , wherein the second volume rendering properties comprise properties for obtaining a contour of the remaining region.

16. The method of claim 11 , further comprising resetting at least one of the first and second volume rendering properties.

17. The method of claim 11 , wherein the second volume rendering properties comprise at least one selected from the group consisting of a threshold, a gamma curve, a post gain, and an image filter.

18. The method of claim 11 , wherein the first volume rendering properties comprise at least one selected from the group consisting of transparency, a color map, a threshold, a gamma curve, a post gain, and an image filter.

19. The method of claim 11 , wherein the first and second medical images comprise a three-dimensional (3D) ultrasound image.

20. The method of claim 19 , further comprising:

transmitting ultrasound signals to an object;

receiving ultrasound echo signals reflected from the object; and

generating the first medical image based on the received ultrasound echo signals.

21. A non-transitory computer-readable recording medium having recorded thereon a program for executing the method of claim 11 .
