Abstract:
1. A method for improving a visualization of an object in an interventional angiographic examination, comprising: acquiring an empty image with pure anatomy, a filling image with vascular tree filled with a contrast agent, and a native image with the object being introduced by a detector of an imaging recording system, the empty image, the filling image, and the native image having a matrix-shaped array of pixels; subtracting the empty image from the filling image for generating a first subtraction image by an image processing system; subtracting the empty image from the native image for generating a second subtraction image by the image processing system; processing the first subtraction image for generating a vessel image by the image processing system; processing the second subtraction image for generating an object image by the image processing system; processing the vessel image and the object image for generating a roadmap image by the image processing system; and playing the roadmap image on a monitor, wherein the vessel image is subtracted from the object image for generating the roadmap image.
