Abstract

A method for providing a virtual contrast agent for blood vessels in a body portion for angioscopy comprising deriving data from a 3D model using, for example, magnetic resonance imaging, computerized tomography (CT), and 3D angio. The data is segmented to provide a segmented 3D model of the blood vessels. A first procedure image is made with a contrast agent present. The 3D model is then registered with the first procedural image and “virtual camera parameters” are obtained. The 3D model is rendered and overlaid onto a second procedure image without contrast, whereby a virtual contrast is achieved.
