Development of Radiological Diagnostic Information System for Dental Practice Based on DICOM-3.0

(1)牙科和口腔放射学诊断图像对DICOM附录的协调32采用面向对象分析方法对口腔内X线片和全景X线片的属性进行了分析。(2)以Oracle8为数据库引擎的CTN图像存储服务器的开发为了管理大量的图像，对CTN软件进行了修改，使其应用Oracle8数据库引擎。为了便于软件开发，创建了一个口腔内X线片的样本对象，包含了附录32中定义的所有属性。(4)用于下颌关节诊断的MRI运动图像的DICOM对象使用Quick算法软件为运动图像定义了一个DICOM SOP类来进行压缩。开发了用于创建对象和显示运动图像的软件系统。(5)口内摄影胶片的自动二次采集系统为实现口腔摄影胶片的有效输入，开发了SCU图像存储软件SOP类。

(1) Harmonization of Diagnostic Image in Dental and Oral Radiology to DICOM Supplement 32Attributes of intaoral radiography and panoramic radiography were analyzed by Object Oriented Analysis. It was found that attribute definitions in DICOM Supplement 32 lacked in attributes for CR images and Secondary Caputre(SC) images.(2) Development of CTN image storage server using Oracle8 as the database engineIn order to manage a large number of images, CTN software was modified to apply Oracle8 database engine. Using it, a DICOM image server/client system was constructed for research and education.(3) Simulation of DICOM object of intraoral radiographyA sample object of intraoral radiography was created for convenience of software development, which included all the attributes defined in Supplement 32.(4) DICOM object of MRI moving image for tmpolomandibular joint diagnosisA DICOM SOP class was defined for moving image using Quick algorithm software for the compression. A software system was developed to create objects and display the moving image.(5) Automatic secondary capturing system for film based intraoral radiographyA SCU software for image storage SOP Class was developed for the effective input of film based intraoral radiography.
