Abstract

The invention relates to a method for presenting a number of two- or three-dimensional images from different modalities registered with each other, with points of interest being able to be assigned to an individual image of the modalities and in all images selectable graphics primitives being overlaid on the assigned points of interest so that a visual assignment of points of interest or area of interest between simultaneously displayed two- or three-dimensional images occurs, as well as an imaging system of a workstation for executing the method.

Claims

1-16. -16. (canceled)

17. A method for simultaneously displaying a plurality of medical images from a plurality of modalities, comprising:

assigning a point of interest to one of the images from one of the modalities; and

overlaying the point of interest in all the images from the modalities with an identifying graphic shape so that the point of interest is visualized between simultaneously displayed images from the modalities.

18. The method as claimed in claim 17, wherein the medical images are three-dimensional or two-dimensional.

19. The method as claimed in claim 18, wherein the three-dimensional images are displayed on a workstation from a three-dimensional volume data set.

20. The method as claimed in claim 17, wherein the point of interest is selected in a sectional plane of a multiplanar reconstruction display.

21. The method as claimed in claim 17, wherein the point of interest which is not visible in one image is shown differently in the other images.

22. The method as claimed in claim 17, wherein the point of interest is overlaid and displayed on a radioscopy image of an examination monitor of a C-arm system.

23. The method as claimed in claim 17, wherein the identifying graphic shape is three-dimensional or two-dimensional.

24. The method as claimed in claim 23, wherein the three-dimensional graphic shape is selected from the group consisting of:

sphere, cube, and rectangular solid.

25. The method as claimed in claim 23, wherein the two-dimensional graphic shape is selected from the group consisting of:

circle, square, rectangle, and cross.

26. The method as claimed in claim 17, wherein the point of interest is assigned with a textual description.

27. The method as claimed in claim 26, wherein the point of interest as well as the assigned textual description are stored and displayed in a list for a further function.

28. The method as claimed in claim 27, wherein the further function is deletion, hiding, or go to point.

29. An imaging system for simultaneously displaying a plurality of medical images from a plurality of modalities, comprising:

a first memory for storing image volume data sets of the images;

a selecting device for selecting a point of interest in one of the images from one of the modalities;

a second memory for storing a location of the point of interest;

a graphics generator for creating a graphic shape for the point of interest; and

a calculating device for overlaying the point of interest in all the images from the modalities with the graphic shape so that the point of interest is visualized between simultaneously displayed images from the modalities.

30. The method as claimed in claim 29, wherein the medical images are three-dimensional or two-dimensional.

31. The imaging system as claimed in claim 29, wherein the second memory stores a textual description assigned to the point of interest.

32. The imaging system as claimed in claim 29, wherein the second memory stores a feature assigned to the point of interest.

33. The imaging system as claimed in claim 29, wherein the imaging system comprises a device for setting a transfer function.

34. The imaging system as claimed in claim 33, wherein the transfer function sets the point of interest been seen within different displays of the one of the images.

35. The imaging system as claimed in claim 29, wherein the imaging system comprises a device for automatically determining the point of interest.
