1. Medical imaging arrangement for accurate positioning for vessel intervention procedures, the arrangement comprising: at least one X-ray image acquisition device; a data processing unit; and a display device; wherein the X-ray image acquisition device is adapted to acquire at least one X-ray image of a vessel region of interest with injected contrast agent and to acquire at least one current fluoroscopy image of the vessel region of interest; wherein the data processing unit is adapted to identify vessel information data within the at least one acquired image; to detect first calcification features of the vessel in the vessel region of interest in the at least one acquired image; to generate vessel representation using the vessel information data and the detected calcification features; to detect second calcification features of the vessel in the vessel region of interest in the at least one current fluoroscopy image, wherein the second calcification features are corresponding to the first calcification features; to register the vessel representation with the fluoroscopy image, wherein the calcification features are used for the registration; to generate a composite image by combining the vessel representation with the at least one fluoroscopy image; wherein the display device is arranged to display the composite image.
