为了设计和验证标准化髁突经咽侧位摄片方法,使显示的髁突影像甲级片率提高,并明显改善该片的重复性,研制了定位摄片架和开口度测量板,使摄片水平角和垂直角保持在5度,摄片距离和髁突位置保持基本固定.与非定位片比较,甲级片率提高3倍,丙级片率降低90%,髁突影像重复率达75%,髁突影像稍有差异者25%.结论是标准化髁突经咽侧位摄影方法可以明显提高髁突显示的甲级片率,降低丙级片率,并有良好的可重复性.
In order to design and verify the standardized method of lateral pharyngeal pharyngeal radiography to improve the conformal imaging grade A and improve the repeatability of condyle imaging, a positioning camera frame and an aperture measuring plate The horizontal and vertical angles were maintained at 5 degrees, and the distance between the radiographs and the position of the condyles remained almost constant.Compared with the unlocated films, the rate of grade A increased by 3 times and that of grade C by 90% 75%, condylar image slightly difference 25% .Conclusion: The standardized condyle pharyngeal lateral pharyngeal photography method can significantly improve the condyle showed Class A film rate, reduce the C film rate, and has good repeatability.
