Abstract
This invention will introduce a fast and effective target approach planning method preferably for needle guided percutaneous interventions using a rotational X-ray device. According to an exemplary embodiment A targeting method for targeting a first object in an object under examination is provided, wherein the method comprises selecting a first two-dimensional image of an three-dimensional data volume representing the object under examination, determining a target point in the first two-dimensional image, displaying an image of the three-dimensional data volume with the selected target point. Furthermore, the method comprises positioning the said image of the three-dimensional data volume by scrolling and/or rotating such that a suitable path of approach crossing the target point has a first direction parallel to an actual viewing direction of the said image of the three-dimensional data volume and generating 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.
