Abstract:
1. A method for targeting a first interventional object of a targeting device to a target point in an object under examination, the method comprising the following steps: receiving in a processor of the targeting device a first two-dimensional image from an imaging device of a three-dimensional data volume representing the object under examination; receiving in the processor a target point in the first two-dimensional image; operating the processor to display an image of the three-dimensional data volume with the selected target point represented as a three-dimensional structure having a distance scale within its image, wherein the three-dimensional data volume is combined with a three-dimensional angiographic volume rendering of the same object under examination; operating the processor to position the image of the three-dimensional data volume by scrolling and/or rotating about the target point center to make a path of approach crossing the target point having a first direction parallel to an actual viewing direction of the said image of the three-dimensional data volume; operating the processor to generate a second two-dimensional image out of the three-dimensional data volume wherein a normal of the plane of the second two-dimensional image is oriented parallel to the first direction and crosses the target point; operating the processor to render the image of the three-dimensional data volume, the three-dimensional structure having a distance scale within its image, and the two-dimensional image under the same perspective, wherein the imaging device is focused on an extension of the path of approach; moving the first interventional object to target the target point in the object under examination according to the path of approach; wherein the path of approach avoids perforation of any vessel in the three-dimensional angiographic volume rendering.
