METHOD, DEVICE AND COMPUTER PROGRAM PRODUCT FOR CAPTURING PROJECTION IMAGES WITH OPTIMISED MOVEMENT PATH

摘要

A method, device, and computer program product for capturing projection images of an object. A beam source is moved by a control unit on a path into a plurality of positions, in which a beam is transmitted. A beam detector is moved by the control unit into a plurality of positions, in which the beam, penetrating the object, is detected. The beam source and/or the beam detector are moved on a calculated path around the object, at a constant distance between the beam source and the beam detector or the object. The path is described by an nth degree polynomial and determined by the control unit through an optimization of a path along the central beam. The polynomial is selected such that a safety clearance with respect to the object is maintained and a distance between the beam detector and the object is minimized.
