A method for representing a blood vessel including a thrombosed section of the blood vessel in a patient is provided. The method includes capturing a first volume data set after administration of a contrast agent, locating a proximal and/or distal end of the thrombosed section of the blood vessel with the aid of the first volume data set, and defining a data capture area for a second volume data set based on the proximal and/or distal end of the thrombosed section of the blood vessel that has been located. The method also includes capturing the second volume data set, segmenting the thrombosed section of the blood vessel from the second volume data set, capturing fluoroscopic images, and superimposing the segmented thrombosed section of the blood vessel with the fluoroscopic images.
