Abstract

A method for creating a selective vessel image within a volume section of an examination object using an imaging system is provided. The method includes creating a vessel image of the volume section. The creating of the vessel image includes acquiring imaging data of the volume section within a predetermined time interval using the imaging system, determining a maximum opacity within the time interval on account of a contrast agent administered to the examination object per pixel of the vessel image, and segmenting vessels. The segmenting includes deciding, depending on the maximum opacity of the pixel, whether the respective pixel belongs to the vessel. The method also includes determining a contrast agent arrival time per pixel of the vessel image, and segmenting whether the respective vessel of the vessel image belongs to a vessel of the selective vessel image.
