The invention relates to a method for determining a trajectory of a motorized X-ray imaging system for acquiring images of a patient to whom a phantom comprising radiopaque fiducials having a known spatial arrangement has been attached so as to be visible on at least one 2D image of a body region of interest acquired by the X-ray imaging system by acquiring one first 2D image of the phantom by the X-ray imaging system in a given position; detecting the fiducials of the phantom in the acquired first image; based on the detected fiducials, determining the position of the phantom in a referential of the X-ray imaging system; determining a set of positions of the X-ray imaging system configured to acquire a set of 2D X-ray images of the region of interest such that the set of 2D X-ray images complies with at least one imposed requirement on the position of the phantom relative to a part of the set of images and combining the set of determined positions to determine a trajectory of the X-ray imaging system with respect to the position of the phantom.
