To observe a catheter (43) advancing in a vessel system, a 3D model of the vessel system is reconstructed with the help of differently oriented X-ray projections (P1A, . . . ) generated by a C-arm system (20) during the injection of a contrast agent. Next, a movement corridor (M) of the catheter (43) is determined from the 3D model. During an examination procedure, current projections (P) are generated showing an image (43′) of the catheter that can be registered with the reconstructed 3D model and/or the movement corridor (M). Based on the registered catheter image and 3D model of the vessel geometry or the movement corridor (M), an optimal projection direction (dopt) is determined and the C-arm system (20) is controlled to orient the next projections in the optimal projection direction.
