Claim One:
1. A system ( 400 ) for estimating a position in an x-ray projection image corresponding to a projected probe position of an intravascular probe ( 422 ) at a time of acquiring data from the intravascular probe ( 422 ), the system comprising: a marker detector ( 404 ) for identifying in the x-ray projection image a plurality of projected positions of markers ( 302 ), the markers being located at predetermined distances along an acquisition trajectory of the intravascular probe; and an interpolator ( 408 ) for interpolating the projected positions to obtain the projected probe position on the acquisition trajectory, the projected probe position corresponding to a location of the intravascular probe ( 422 ) at a time of acquiring the data, in dependence on a distance along the acquisition trajectory between the intravascular probe ( 422 ) at the time of acquiring the data and at least one of the markers ( 302 ).
