Abstract: 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 re

Abstract: The invention relates to a method for controlling movement of a motorized C-arm, comprising: receiving position information of a user (U) relative to the C-arm (1), continuously receiving current position information of the C-arm (1) relative to a reference position of the C-arm, from said current position information and from the position information of the user, computing a graphical representation of the current position of the C-arm according to the user's point of view, from the computed graphical representation of the current position of the C-arm, computing a graphical representation of at least one command button suited to the current position information of the C-arm and to the user's point of view to move the C-arm in a determined direction according to a respective degree of freedom, displaying on a control panel a graphical user interface (7) comprising said computed representation (70) of the current position of the C-arm and said at least one command button (710).

Abstract: 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

Abstract: The present invention relates to a method for reconstructing a 3D image from 2D X-ray images acquired with an X-ray imaging system, said method comprising the steps of: a) receiving a set of 2D X-ray images of a region of a patient with said X-ray imaging system, b) computing an initial 3D image within the coordinate system of the X-ray imaging system by using at least part of said 2D X-ray images with their respective projective geometry data; c) projecting said initial 3D image on at least part of said 2D X-ray images and adjusting the respective projective geometry data of said images, said adjustment comprising registration of said images with the projection of the initial 3D image using an image-to-image registration technique; d) computing an updated 3D image using the complete set of 2D X-ray images with their respective adjusted projective geometry data.
