The invention relates to an imaging (X-ray) system for observing the motion of an object in the vascular system of a body volume ( 10 ). An X-ray apparatus ( 3 ) in this system generates two-dimensional projection images ( 4 ) of the body volume ( 10 ). In a module ( 5 ) the position of the tip of the object is determined from the projection images and this position is associated, in a further module ( 2 ), with a previously acquired three-dimensional representation ( 1 ) of the vascular system. The module ( 2 ) then calculates optimum imaging parameters which involve notably a planar projection of the tip of the object and a minimum projection window. These parameters are subsequently set on the X-ray apparatus ( 3 ) so as to serve as a basis for the next two-dimensional image ( 4 ).
