Patent ID: 7494277

Claim:
A method for eliminating error elements caused by movements of an imaged object in X-radiography, said method comprising performing X-radiography on an imaged object for compiling X-radiographic information, characterized in that a model geometry is created of an X-ray imaging process, said creation work comprising a determination of the location for two or more position markers in a set of coordinates graded for an X-ray imaging apparatus, when X-radiography of an imaged object is completed, predictions are worked out regarding the locations of position markers during the imaging session, the locations and predictions determined on the basis of the model geometry are used as a basis for defining projected or most likely locations for the position markers, an automatic position markers identification method is applied for finding the locations of position markers from within a search area in the X-radiographic information, and when the locations of at least two position markers have been found with the automatic position markers identification method, an adjustment of offsets is performed between the projected locations of position markers and the locations of position markers looked up by the automatic identification method for eliminating the error elements resulting from movements of an imaged object.
