In order to practically include the intra-oral radiography into the digital filing system such as PACS, we developed in this study a system which automatically unwraps a dental film package, processes the film and digitizes the image. It takes about 8 minutes to process a film and the throughput of the system was 80 seconds per film. The minimum pixel size of the digitized image was 40μm and the resultant digital image quality was good enough for the diagnosis in a similar detail to the original film image. A filing system using a DICOM sever was connected to the digitizer through 10 base-T Ethernet cable. The software for the DICOM server was e-Film Version 1.320 which was developed by Mount Sinai Hospital in Canada and the functions included C-Store Service Class Provider, its User, Query/Retrieve Service Class Provider, its User and viewing function.

为了实际地将口腔内x线摄影纳入PACS等数字档案系统，我们开发了一种自动打开牙科胶片包装，处理胶片并将图像数字化的系统。处理一张胶片大约需要8分钟，系统的吞吐量为每张胶片80秒。数字化图像的最小像素尺寸为40μm，所得到的数字图像质量足以在与原始胶片图像相似的细节上进行诊断。使用DICOM服务器的文件系统通过10 base-T以太网电缆连接到数字化仪。DICOM服务器的软件是加拿大西奈山医院开发的e-Film Version 1.320，其功能包括C-Store服务类提供商、其用户、查询/检索服务类提供商、其用户和查看功能。
