Development of Radiological Information System for Dentistry Based on DOCOM-3.0

(1)牙科放射图像信息分析为了与已经安装的DICOM系统通信，牙科和全景图像对象将是CR或SC的常规IOD。然而，以下属性不能由本标准中定义的元素来描述，并且标签是在阴影组中新定义的。(2)牙科放射信息系统(D-RIS)工作站的开发我们设计了一个基于CTN软件的牙科RIS软件系统，该软件是支持DICOM功能的免费软件，包括图像数据库服务器。D-RIS支持存储和查询/检索服务，包括检查方式、检查地点、摄影技术和投影角…等关键要素为了更好地应用于DICOM Suppl.32，正在开发一些子程序，将摄像机和35 mm胶片扫描仪连接到工作站上，以输入样本图像。开发了将图像数据转换为DICOM格式的软件。为了在临床中使用，似乎需要一种比视频摄像机更高的图像质量和比胶片扫描仪更快的处理速度的输入设备。(3)与订购系统的接口设计在本设计中，我们的医院信息系统通过查询患者ID来生成一天中唯一的研究ID、患者信息、站点等。利用这些信息，我们设计了生成DICOM对象的软件。(4)远程放射试验我们还开发了一个软件系统，通过互联网接收图像和解释命令，编辑报告，并进行回复。我们在东京医科大学和九州大学之间测试了该系统。DICOM对象的口腔内X光照相转移了大约15分钟。较少

(1) Analysys of Radiological Image Information in DentistryFor the communication with the DICOM system already installed, dental and panorama image objects will be conventional IOD of CR or SC.The following attributes, however, cannot be described by the elemts defined in the present standards, and tags were newly defined in the shadow groupes. (Description of kind of the image DENTAL/PANORAMA,Site of the Examination, Radiographing Technique, Angulation of Projection, Size of Film/Cassette)The prototype developed in 1996 was reviced to support the additional standards defined in DICOM supplement 32, Sep.1997.(2) Development of Dental Radiological Information System (D-RIS) WorkstaionWe designed a RIS software system for dentistry based on the CTN software, which was freeware suprting DICOM functions incluging the image database server. The D-RIS suports the STORAGE and QUERY/RETRIEVE service with key elements of modality, site of examination, radiographing technique and projection angl … More e. for the application to DICOM Suppl.32, some subprograms are presentry under construction.A video camera and 35mm film scanner were connected to the workstation to input the sample images. A software was developed to convert the image data to the DICOM format. For the utilization in the clinical office, an input device seemed to be required which had higher image quality than the video camra and faster processing speed than the film scanner.(3) Design of the interface to the Ordering SystemOur Hospital Information System, in the present design, generates a study ID unique in a day, patient information, site, ets., by the query with patiesnt ID.Using these information, we design the software for generating a DICOM object.(4) Trials of Tele-RadiologyWe also developed a software system to recieve the image and interpretation order through the Internet, edit the report, and reply it. We tested the system between Tokyo Medical and Dental University and Kyushu University. The DICOM objectd of a intraoral radiography transfered about fifteen minutes. Less
