X-ray images are recorded during the system dose regulation phase with pure anatomy and during the filling phase with the vessels filled with contrast agent. A mask image is produced from both of the images. Native X-ray images are produced during a working or intervention phase with an object, for example a wire, a catheter or a “coil”, moved in the vessel. The images have a matrix-shaped array of pixels. The pure anatomy images are subtracted from the filling images and from the native images for generating a first subtraction image and a second subtraction image respectively. The first and the second subtraction image are processed for generating a vessel image and an object image respectively. The vessel image and the object image are processed for generating a roadmap image which is played back on a monitor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for enhanced visualization of objects in interventional angiographic examinations","description":"A method for enhanced visualization of objects in interventional angiographic examinations is provided.
