METHOD FOR CALIBRATING A DUAL X-RAY IMAGING DEVICE AND METHOD FOR OBTAINING A THREE-DIMENSIONAL POSITION OF A POSTOPERATIVE ARTICULATION USING THE CALIBRATING METHOD CAPABLE OF OBTAINING ACCURATE TWO-DIMENSIONAL IMAGE DATA OF A POSTOPERATIVE ARTICULATION
METHOD FOR CALIBRATING A DUAL X-RAY IMAGING DEVICE AND METHOD FOR OBTAINING A THREE-DIMENSIONAL POSITION OF A POSTOPERATIVE ARTICULATION USING THE CALIBRATING METHOD CAPABLE OF OBTAINING ACCURATE TWO-DIMENSIONAL IMAGE DATA OF A POSTOPERATIVE ARTICULATION
PURPOSE: A method for calibrating a dual X-ray imaging device and method for obtaining a three-dimensional position of a postoperative articulation using the calibrating method are provided to accurately set the relative positions of an X-ray irradiating unit and a sensing unit for a postoperative articulation in the dual X-ray imaging device, thereby obtaining accurate two-dimensional image data of a postoperative articulation.;CONSTITUTION: The magnification between a sensing unit and an X-ray image is set(ST100). An X-ray is irradiated to a calibration cube from an X-ray irradiating unit. An X-ray passing through the calibration cube is sensed by the sensing unit. The horizontal and vertical distances between projection points on the X-ray image are measured. The magnification of the sensing unit about the X-ray image is set by horizontal and vertical directions.;COPYRIGHT KIPO 2011
