Abstract

A method and system for medical image display comprising means for acquiring two-dimensional images; means for displaying images; means for managing the display of a three-dimensional representation on the means display and for automatically orienting the three-dimensional representation according to at least one operating parameter of the means for acquisition means so that the three-dimensional representation is viewed on the means for display from a viewpoint corresponding to that from which the means for image acquisition acquire or have acquired a two-dimensional image.

Claims

1. A system for medical imaging comprising:

(a) means for acquiring two-dimensional images;

(b) means for displaying images; and

(c) means for managing the display of a three-dimensional representation on the means for display and for automatically orienting the three-dimensional representation according to at least one operating parameter of the means for acquisition so that the three-dimensional representation is viewed on the means for display from a viewpoint corresponding to that from which the means for acquisition images acquire or have acquired a two-dimensional image.

2. The system according to claim 1 wherein:

(a) the means for display comprises means for displaying a two dimensional image acquired in real time at the same time as displaying the three-dimensional representation; and

(b) the means for managing comprises means or automatically orienting the three-dimensional representation according to at least one operating parameter of the acquisition means so that the three-dimensional representation is viewed on the means for display from a viewpoint corresponding to that of the image acquired in real time by means of the means for acquiring images.

3. The system according to claim 1 comprising:

(a) means for storing images previously acquired, with at least one operating parameter of the means for acquiring images during imaging corresponding to these images;

(b) means for display means displaying a two-dimensional image previously acquired at the same time as displaying the three-dimensional representation; and

(c) means for managing automatically orienting the three-dimensional representation according to the operating parameter or parameters stored with an image previously acquired, so that the three-dimensional representation is viewed on the means for display from a viewpoint corresponding to that from which the image was previously acquired.

4. The system according to claim 2 comprising:

(a) means for storing images previously acquired, with at least one operating parameter of the means for acquiring images during imaging corresponding to these images; and

(b) means for display means displaying a two-dimensional image previously acquired at the same time as displaying the three-dimensional representation; and

(c) means for managing automatically orienting the three-dimensional representation according to the operating parameter or parameters stored with an image previously acquired, so that the three-dimensional representation is viewed on the means for display from a viewpoint corresponding to that from which the image was previously acquired.

5. The system according to claim 2 wherein the means for managing automatically translates the three-dimensional representation and centers it in the same way as a two-dimensional image acquired in real time or previously acquired.

6. The system according to claim 3 wherein the means for managing automatically translates the three-dimensional representation and centers it in the same way as a two-dimensional image acquired in real time or previously acquired.

7. The system according to claim 4 wherein the means for managing automatically translates the three-dimensional representation and centers it in the same way as a two-dimensional image acquired in real time or previously acquired.

8. The system according to claim 1 wherein the means for managing automatically adjusts the scale of the three-dimensional representation with respect to a two-dimensional image acquired in real time or previously acquired.

9. The system according to claim 2 wherein the means for managing automatically adjusts the scale of the three-dimensional representation with respect to a two-dimensional image acquired in real time or previously acquired.

10. The system according to claim 3 wherein the means for managing automatically adjusts the scale of the three-dimensional representation with respect to a two-dimensional image acquired in real time or previously acquired.

11. The system according to claim 4 wherein the means for managing automatically adjusts the scale of the three-dimensional representation with respect to a two-dimensional image acquired in real time or previously acquired.

12. The system according to claim 5 wherein the means for managing automatically adjusts the scale of the three-dimensional representation with respect to a two-dimensional image acquired in real time or previously acquired.

13. The system according to claim 6 wherein the means for managing automatically adjusts the scale of the three-dimensional representation with respect to a two-dimensional image acquired in real time or previously acquired.

14. The system according to claim 7 wherein the means for managing automatically adjusts the scale of the three-dimensional representation with respect to a two-dimensional image acquired in real time or previously acquired.

15. The system according to claim 1 comprising means for enabling an operator to control the storage of parameters corresponding to one or more preferred orientations for the three-dimensional representations and to display the three-dimensional representations with these orientations.

16. The system according to claim 1 comprising means for enabling an operator to control the storage of three-dimensional representations and to control the display of these representations.

17. The system according to claim 1 comprising means for reconstructing three-dimensional representations from plates acquired on this same system by X-ray imaging.

18. The system according to claim 1 comprising means for reconstructing three-dimensional representations from plates acquired by CT or MRI tomography.

21. The method according to claim 19 wherein the adjustment of the three-dimensional image representation comprises one or more of the following with respect to the view point of the two-dimensional image:

orientation or scaling or centering.

19. A method for medical imaging comprising:

(b) transmitting desired parameters relating to the two-dimensional image;

(c) acquiring a three-dimensional image representation of the two-dimensional image; and

(d) adjusting the three-dimensional image representation so that the representation substantially corresponds to the same viewpoint as the two-dimensional image.

22. The method according to claim 20 wherein the adjustment of the three-dimensional image representation comprises one or more of the following with respect to the view point of the two-dimensional image:

orientation or scaling or centering.

23. The method according to claim 20 wherein the pre-recorded two-dimensional images are of one or more orientations of an anatomical region to be studied.
