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

(1)牙科放射影像信息的分析为了与已安装的DICOM系统进行通信，牙科和全景影像对象将是CR或SC的常规IOD。然而，以下属性不能用现有标准中定义的元素来描述，并且在阴影组中新定义了标记。（牙齿/全景图像类型、检查部位、X线摄影技术、投影角度、胶片/暗盒尺寸的描述）对1996年开发的原型进行了修订，以支持DICOM补充32（1997年9月）中定义的附加标准。(2)牙科放射信息系统（D-RIS）工作站的研制我们设计了一个基于CTN软件的牙科放射信息系统软件系统，该软件是一个支持DICOM功能的免费软件，包括图像数据库服务器。D-RIS支持检索和查询/检索服务，包括模态、检查部位、X线摄影技术和投影角度等关键要素 ...更多信息 e.为了应用于DICOM Suppl.32，目前正在构建一些子程序。摄像机和35 mm胶片扫描仪连接到工作站以输入样本图像。开发了一个软件将图像数据转换为DICOM格式。为了在临床办公室中使用，似乎需要一种输入设备，其图像质量比视频摄像机高，处理速度比胶片扫描仪快。(3)订购系统接口的设计在本设计中，我们的医院信息系统生成一天中唯一的研究ID、患者信息、研究中心等，利用这些信息，我们设计了一个DICOM对象生成软件。(4)远程放射学的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，编辑报告并回复。我们在东京医科齿科大学和九州大学之间测试了该系统。口内X线摄影的DICOM对象传输约15分钟。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
