摘要：
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 (30) 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, the method comprising the following steps:acquiring one first 2D image of the phantom (30) by the X-ray imaging system in a given position；detecting the fiducials of the phantom (30) in said acquired first image；based on said 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 adapted to acquire a set of 2D X-ray images of the region of interest such that said set of 2D X-ray images complies with at least one imposed requirement on the position of the phantom relative to a part of said set of images,combining said set of determined positions to determine a trajectory of the X-ray imaging system with respect to the position of the phantom (30).
