Classification: CPC G | IPC G

Claim 0:
1. A non-destructive method (1) for inspection of an item, the method comprising:
acquiring (2) a projection image of the item using a radiation imaging system;
obtaining (3) a plurality of simulated projection images of the item or at least one component thereof, based on a simulation of a numerical three-dimensional model of the item or the at least one item component, in which at least one geometric parameter relating to the relative orientation between the simulated item, a simulated radiation source, and a simulated detection plane varies over the plurality of simulated projection images;
determining (4) a relative orientation of the item with respect to the radiation imaging system, said determining of the relative orientation comprising comparing (9) the acquired projection image to the plurality of simulated projection images, and selecting at least one simulated projection image with the highest image similarity measure to the projection image;
determining (5) at least one angle of rotation taking a viewing angle and the relative orientation with respect to the selected simulated projection image into account;
moving (6) the item and/or the radiation imaging system in accordance with the at least one angle of rotation;
acquiring (7) a further projection image of the item, after moving the item and/or the radiation imaging system, such that the further projection image corresponds to a view of the item from the viewing angle.
