分析研究牙科全景X射线摄影原理，以及牙弓形态对全景摄影的影响，提出优化设计的主要指导原则，提高其图像质量。分析全球人群的牙弓形态特征参数，对特定的全景摄影运动轨迹进行优化。牙科全景X射线摄影成像效果有诸多影响因素，断层曲线的设计对设备成像会产生决定性影响，尤其是对尖牙部分。优化断层曲线设计可缩小水平垂直放大倍率变化范围，减少几何失真和牙齿重叠。

Through the analysis on principles of dental panoramic radiography, we analyzed the influence factors of the dental arch, and provided the main principles for optimizing design to improve the image quality. Through the analysis on the human dental arch’s form, we optimized the radiographic procedure. Many factors affect the quality panoramic image, but the focal trough’s design is one of the most important factors, especially for canine regions. Optimizing design of focal trough can lessen degrees of horizontal and vertical magnification, also can reduce geometric distortion and overlapped images of teeth.
