Abstract. In order to gain maximal insight in the vascular morphology during minimal invasive treatment of vascular pathologies, high resolu-tion 3D Rotational Angiography (3DRA) data is acquired and visual-ized peri-operatively. The 3D data provides good understanding of the vasculature, however in case of complex structures (e.g. liver and neuro-vasculature, and arteriovenous malformations) there is a distinct added value in showing a stereoscopic visualization to the clinician. In order to provide such a stereoscopic image, a 42 ” autosterescopic nine-view lenticular screen was mounted in the Operating Room (OR). To opti-mally assist the intervention, the stereoscopic visualization of the vascu-lature can be presented from the same viewing incidence as the real-time X-ray image, which is used to guide the intra-vascular devices, such as catheters and stents. The GPU-based implementation offers interactive manipulation throughout. 1
