A prototype system for digital panoramic imaging of the maxillofacial complex has been developed. In this system x-ray film is replaced by an electronic sensor that delivers the image information to a computer for storage in digital format. The images, which are similar to conventional panoramic radiographs, are displayed on a high-resolution video monitor and may be stored on optical disk for future use. Hard-copy output is also available. The present prototype system has been installed on an Orthopantomograph model OP10 panoramic x-ray machine is programmed for operation with this machine, but in principle the system can be installed on any such device. The system may be incorporated into the design of future panoramic x-ray systems or may be used to retrofit panoramic x-ray systems now using photographic film to record the radiographic image. Greater sensitivity of electronic sensors should make possible a reduction of x-ray dose to the patient, compared with film-based systems.
已开发出一种用于颌面复合体数字全景成像的原型系统。在该系统中，电子传感器取代了X光胶片，该传感器将图像信息传送到计算机以数字格式存储。这些类似于传统全景X光片的图像显示在高分辨率视频监视器上，并可存储在光盘上以供将来使用。也可提供硬拷贝输出。目前的原型系统已安装在一台OP10型全景X光机上，已针对该机器进行编程操作，但原则上该系统可安装在任何此类设备上。该系统可纳入未来全景X光系统的设计中，或可用于对目前使用摄影胶片记录X光图像的全景X光系统进行改造。与基于胶片的系统相比，电子传感器更高的灵敏度应能降低患者所接受的X光剂量。
