Medical navigation image output comprising virtual primary images and actual secondary images
First Claim
1. An image output method for medical navigation in which the positional relationship of a trackable instrument with respect to a part of a patient'"'"'s body is ascertained, and in which the trackable instrument and the part of the patient'"'"'s body are displayed in real time in the correct positional relationship on an image output, the method comprising:
- displaying in real time the part of the patient'"'"'s body based on virtual image data captured via a medical imaging method and on actual images captured in real time during navigationwherein the virtual image data is displayed on the image output as the primary basis of the image and the actual images captured in real time are correlated with and added into the virtual images as the secondary basis of the image so as to augment the virtual images, wherein the actual images are confined to at least one continuous area of the image output that constitutes less than 50% of the overall area of the image output assembled by the virtual image data and the actual images, and wherein capturing the actual images comprises capturing the actual images using a video image capture unit arranged on the trackable instrument.

Abstract
The invention relates to an image output method for medical navigation in which the positional relationship of an instrument with respect to a part of a patient'"'"'s body is ascertained, and in which the instrument and the part of the patient'"'"'s body are displayed in the correct positional relationship on an image output, wherein the display of the part of the patient'"'"'s body is based on the one hand on virtual image data captured by means of a medical imaging method and on the other hand on actual images captured during navigation, wherein the virtual image data is displayed on the image output primarily and as the basis of the image, and the actual images are superimposed on it merely as an addition and secondarily. It also relates to an image generating and image output device for medical navigation.

22. An image generating and image output device for medical navigation in which the positional relationship of a trackable instrument with respect to a part of a patient'"'"'s body is ascertained, comprising:
-
an image output on which the trackable instrument and the part of the patient'"'"'s body are displayed in the correct positional relationship; an image processor which generates in real time a display of the part of the patient'"'"'s body on the basis of virtual image data captured via a medical imaging method and on the basis of actual images captured in real time during navigation, a video image capture unit configured to be arranged on the trackable instrument, said video image capture unit configured to provide the actual images; and an image display control which displays the virtual image data on the image output as the primary basis of the image, wherein the actual images are correlated with and added into the virtual image data as the secondary basis of the image so as to augment the virtual images, wherein the actual images are confined to at least one continuous area of the image output that constitutes less than 50% of the overall area of the image output assembled by the virtual image data and the actual images.
