ABSTRACT:
To reduce the contrast fluid and X-ray load on patients during interventional procedures, a real-time visualization architecture combines 2D live images with 3D reconstructed volume information. In general, 2D X-ray images are 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, the 3D information is displayed 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 combined with silhouette rendering maintains the contrast in the 2D information while preserving the 3D impression.
