ELECTRONIC FILING AND APPLICATION OF INTRAORAL RADIOGRAPHIC IMAGES IN DENTAL INFORMATION SYSTEM

为了将口腔内X线片实际应用到PACS等数字化归档系统中，本研究开发了一种自动打开牙科胶片包、对胶片进行处理并将图像数字化的系统。处理一张胶片大约需要8分钟，系统的吞吐量是每张胶片80秒。数字化图像的最小像素尺寸为40μm，生成的数字图像质量足够好，能够以与原始胶片图像相似的细节进行诊断。使用DICOM服务器的文件系统通过10BASE-T以太网线连接到数字化仪。DICOM服务器的软件是加拿大西奈山医院开发的e-File1.320版，其功能包括C-Store服务类提供者、其用户、查询/检索服务类提供者、其用户和查看功能。

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.
