X-RAY EXAMINATION DEVICE AND METHOD FOR PRODUCING UNDISTORTED X-RAY IMAGES |
摘要 |
In an X-ray examination device and a method for generating distortion-free X-ray images the imaging properties are calculated and distortions are corrected by providing at least one calibration member (7, 8) for forming a reference pattern; a correction unit (13) corrects the distortions in X-ray images on the basis of the pattern of the calibration members (7, 8) actually formed in the patient X-ray image (FIG. 4) and the calculated reference pattern. |
