10. The system according to claim 1, wherein the display means is arranged for:

displaying the initial representation of the multi-dimensional image and the annotation located therein, using a display setting; and

after receiving the visualization request, displaying the preferred representation of the multi-dimensional image and the annotation located therein, using the same display setting.

11. The system according to claim 10, wherein the display setting is indicative of a display contrast of the initial representation of the multi-dimensional image and the annotation located therein.

12. A workstation comprising the system according to claim 1.

13. An imaging apparatus comprising the system according to claim 1.

29. The system of claim 1, wherein the representation data identifies the representation of the multi-dimensional image displayed to the user at the time the annotation was created.

30. The system of claim 1, wherein the representation data comprises parameters of a plane equation, parameters of a projection matrix, or a parameter indicative of a particular one of lower-dimensional images.

14. A method of displaying a multi-dimensional image and an annotation located therein, the method comprising:
