摘要： The intention relates to a system (1) and a corresponding method for automatic roadmapping for endovascular interventions. In order to enable an enhanced roadmapping visualization without unnecessary device-footprints, the system (1) comprises: an x-ray imaging device (3) for acquiring x-ray images and a calculation unit (5). The x-ray imaging device (3) is adapted for acquiring a first x-ray image (21) with an interventional device (17) present in the vessels (19) while no contrast agent is present in the vessels (19). Furthermore, the x-ray imaging device (3) is adapted for acquiring a second x-ray image (23) with the interventional device (17) present in the vessels (19) while contrast agent is present in the vessels (19). The calculation unit is adapted for creating a roadmap image (27) by subtracting the first x-ray image (21) from the second x-ray image (23). Moreover, the calculation unit (5) is adapted for automatically minimizing the visibility of the interventional device (17) in the roadmap image (27). A display unit (7) is adapted to display the roadmap image (27) or an overlay of a current fluoroscopy image (31) with the roadmap image (27).
