Abstract
A method and image processing system for correcting motion artefacts in captured projection images of a body part caused by movement relative to the co-ordinate system of an imaging system between capture of the images are described. A first image data set is obtained representing a first captured image of the body part for which the imaging system had a first geometry. A second image data set is obtained representing a second captured image of the same body part for which the imaging system had a second geometry and in which the second captured image is from a different direction to the first captured image. The position of at least a first anatomical landmark point is identified in the first captured image from first image data set. The position of the at least first anatomical landmark point is projected into the second captured image. A transformation required to map the position of the same anatomical landmark point from the second image data set onto the projected position of the at least first anatomical landmark is determined. The so determined transformation represents the true position of the body part relative to the imaging system when the second image was captured.
