Abstract:
1. A method for supplying a 3D X-ray image data record for a moving object comprising highly X-ray radiation-absorbent material, comprising: acquiring a plurality of 2D X-ray image data records of the moving object; calculating a 3D X-ray image data record from the 2D X-ray image data records; calculating a plurality of motion fields corresponding to the 2D X-ray image data records respectively; processing the 3D-X-ray image data record for emphasizing a contour of the highly absorbent material; calculating a plurality of 2D forward projections from the processed 3D X-ray image data record corresponding to the 2D image data records using the motion fields respectively; processing the 2D forward projections for changing data values in regions enclosed by the contour to reduce an effect of a high level absorption; and calculating a further 3D X-ray image data record from the processed 2D forward projections using the motion fields.
