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

(1)口腔和口腔放射学诊断图像与DICOM增补32的一致性采用面向对象的分析方法分析了口腔放射学和全景放射学的属性。发现DICOM Supplement 32中CR图像和Secondary capture （SC）图像的属性定义存在缺失。(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，采用Oracle8数据库引擎。利用它，构建了一个用于研究和教学的DICOM镜像服务器/客户端系统。(3)口腔内放射成像DICOM对象的仿真为了方便软件开发，我们创建了一个口腔内放射成像样本对象，它包含了附录32中定义的所有属性。(4)颞下颌关节诊断MRI运动图像DICOM对象使用Quick算法软件对运动图像定义DICOM SOP类进行压缩。开发了一个软件系统来创建对象和显示运动图像。(5)基于胶片的口腔内x线摄影自动二次采集系统为实现基于胶片的口腔内x线摄影的有效输入，开发了图像存储SOP类SCU软件。

(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.
