Method to detect and indicate inaccuracies in long length imaging

1. A method of generating radiation images of a body, each of said radiation images being generated by subjecting the same set of partial radiation images to a different computer-implemented stitching method, each of said partial radiation images comprising part of the radiation image of said body and being generated by multiple shot irradiation and read out of a direct radiography detector,

wherein

one of said stitching methods is based on the reconstruction of the radiation image of an object of known geometry which is irradiated together said body so that each of said partial images comprises part of the radiation image of said body and part of the radiation image of said object of known geometry and

wherein another of said stitching methods is performed on the basis of theoretical stitching parameters originating from the set-up used for said multiple shot irradiation and

at least one value indicative of a deviation between the radiation images resulting from application of said different computer-implemented stitching methods to the same set of partial images is determined and a computer-controlled warning is generated if said value(s) exceeds a preset acceptance value(s).

2. A method according to claim 1 wherein one of said stitching methods is performed by user interaction and another is performed on the basis of reconstruction of the recorded image of said object of known geometry.

3. A method according to claim 1 wherein one of said stitching methods is performed by user interaction and another is performed on the basis of theoretical stitching parameters originating from the set-up used for said multiple shot irradiation.

4. A method according to claim 1 wherein said warning is an indication of patient movement.

5. A method of generating radiation images of a body, comprising:

generating a set of partial radiation images of said body by multiple shot irradiation and read out of a direct radiography detector;

stitching the partial radiation images into stitched radiation images using different stitching methods, wherein one of the stitching methods is based on the reconstruction of the radiation image of an object of known geometry which is irradiated together said body so that each of said partial images comprises part of the radiation image of said body and part of the radiation image of said object of known geometry and wherein another of said stitching methods is performed on the basis of theoretical stitching parameters originating from the set-up used for said multiple shot irradiation; and

generating at least one value indicative of a deviation between the radiation images resulting from application of said different stitching methods to the same set of partial images; and

generating a computer-controlled warning if said value exceeds a preset acceptance value.
