To reduce the contrast fluid and X-ray load on patients during interventional procedures, a real-time visualisation architecture is proposed to combine 2D live images with 3D reconstructed volume information. In general, 2D X-ray images arc recorded from below (Posterior Anterior) and presented head up (Anterior Posterior) by applying a mirroring operation on the image data. In order to ensure a correct alignment of the 2D live images within the reconstructed 3D volume, as is proposed to display the 3D information under the same inverse viewing angle as the 2D live images by applying a mirroring around the Y-axis to the 3D information and by presenting the 3D information in a reverse sorting order. Furthermore, transparent surface/volume rendering may be combined with silhouette rendering to maintain the contrast in the 2D information while preserving the 3D impression.
