摘要
在头颅正位、侧位定位片的基础上增加2张斜位定位片,从不同角度0°,45°,90°和135°拍摄4张X线头颅定位片,并从中重构出颅颌骨的特征点,并同时对误差进行校正.
In 3D positioning of cranio-maxillary bone based on X-films, we add two oblique position scout views on the base of A-P（anterior-posterior） and side position ones. as a result, we obtain 4 scout views of cranio-maxillary bone in its X-films with regard to 0°, 45°, 90°and 135°positions respectively. By this improvement we reconstruct the characteristic points of the cranio-maxillary bone, and at the same time correct the errors.
