Abstract
The invention relates to a method for high-resolution display of vessel implants in angiographic images, featuring the steps: recording at least two images of an object-catheter combination including catheter markers with a medical imaging method; detection of an region of interest created in the form of an area between the balloon markers which completely contains the object to be registered for each recorded image; coarse registration of the region of interest images by registration of the respective pairs of balloon markers of all recorded images; fine registration of the region of interest image content/of the region of interest image by registration of the region of interest content; and arithmetic averaging across the fine-registered images.
