Abstract
The present invention relates to a method, which assists a doctor for instance in orientation in 2D fluoroscopy images. The present invention relates here to a method for displaying co-registered 2D-3D images in medical imaging, comprising the following steps: determine a 3D or 2D projection which is congruent with a 2D image from a 3D image data set, and overlaid display of the 2D image with the 3D or 2D projection on a monitor, characterized in that the two image parts of the two overlaid images can be adjusted and a shift in the two overlaid images which can be adjusted in at least one direction is enabled.

9. A method for improving a 3D visualization of both a vascular insert and a vessel anatomy surrounding the insert in a patient using a radiography during a medical intervention procedure, comprising:
-
determining a 2D projection from a 3D image data set of the patient which is congruent with a 2D image containing the insert; and
overlaying the 2D image with the 2D projection on a monitor, wherein a cross fading of the two image parts of the overlaid image is adjustable, and wherein a shift in one of the two image parts of the overlaid image is adjustable in a direction with an identical position marked in both the shifted and unshifted images and the marked identical position is selected by a user. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A device for improving a 3D visualization of both a vascular insert and a vessel anatomy surrounding the insert in a patient using a radiography during a medical intervention procedure, comprising:
-
a fluoroscopy device for recording a 2D image containing the insert;
a memory for storing a 3D image data set of the patient which is recorded prior to the procedure;
a processing device for determining a 2D projection from the 3D image data set which is congruent with the 2D image and overlaying the 2D image with the 2D projection; and
a monitor for displaying the overlaid image, wherein a cross fading of the two image parts of the overlaid image is adjustable, and wherein a shift in one of the two image parts of the overlaid image is adjustable in a direction with an identical position marked in both the shifted and unshifted images and the marked identical position is selected by a user. - View Dependent Claims (19, 20, 21, 22, 23)
