Abstract

A method and system for multiple view volume rendering are provided. The method includes identifying a plurality of view directions relative to an image of an object and automatically volume rendering a volumetric data set based on the plurality of view directions. The method further includes generating an image for each view direction using the rendered data.

Claims

1. A method for generating multiple image views of an object, the method comprising:

identifying a plurality of view directions relative to an image of an object;

automatically volume rendering a volumetric data set with a processor based on the plurality of view directions;

generating an image for each view direction with the processor using the rendered data;

modifying one of the plurality of view directions;

automatically modifying the other of the plurality of view directions with the processor to maintain the relative positions between the plurality of view directions; and

generating with the processor a second image for each of the plurality of view directions using the rendered data after said automatically modifying the other of the plurality of view directions.

2. A method in accordance with claim 1 wherein the view directions are automatically selected.

3. A method in accordance with claim 1 further comprising receiving a user input defining the plurality of view directions.

4. A method in accordance with claim 1 further comprising identifying a plurality of crop planes with corresponding view directions.

5. A method in accordance with claim 4 further comprising receiving a user input based on a cropping command that defines the plurality of crop planes.

6. A method in accordance with claim 4 wherein at least some of the crop planes are overlapping and with different sides of the overlapping crop planes used for generating an image.

7. A method in accordance with claim 4 wherein the crop planes are intersecting and the resulting displays show a plurality of non-intersecting images displaying only a subset of crop operations.

8. A method in accordance with claim 4 further comprising using anatomical structure markers to identify the plurality of crop planes.

9. A method in accordance with claim 4 further comprising using anatomical structure markers to align the plurality of crop planes.

10. A method in accordance with claim 1 wherein the image volumetric data set comprises a single three-dimensional ultrasound data set stored in a memory.

11. A method in accordance with claim 1 further comprising simultaneously displaying the plurality of images.

12. A method in accordance with claim 1 further comprising automatically defining a plurality of crop planes used in the rendering.

13. A method for visualization of multiple volume renderings of a volumetric data set, the method comprising:

identifying at least one crop plane on the volumetric data set;

automatically generating a plurality of different views with a processor using the volumetric data based on the at least one crop plane;

displaying on a single display images of the plurality of different views;

modifying one of the plurality of different views; and

automatically modifying with the processor the other of the plurality of different views maintain the relative positions between the plurality of views.

14. A method in accordance with claim 13 further comprising identifying view directions defining the different views, the view directions being one of user defined and predefined.

15. A method in accordance with claim 13 further comprising identifying view directions defining the different views and combining the view directions with the at least one crop plane.

16. A method in accordance with claim 13 further comprising volume rendering image data that is one of (i) stored and (ii) currently being acquired for use in automatically generating the different views.

17. A method in accordance with claim 16 wherein the volume rendering is performed on a single three-dimensional (3D) ultrasound data set stored in a memory.

18. A method in accordance with claim 13 further comprising automatically changing the different views based on a change in at least one of the views.

19. The method in accordance with claim 13 further comprising displaying on the single display a second image for each of the plurality of different views based on the volumetric data set after said automatically modifying the plurality of different views.
