The study of standardlization of three-dimentional analysis on oral and dentfacial form.

三维分析的基础数据对于三维图像的保存形式，像体素模型、表面模型(实体模型)和树脂复制品模型等应用领域分为许多主题。人们认为包含所有这些图像信息的文件格式标准化是不可能的，几何文件对体素模型的保存效果很好。表面模型(实体模型)是DXF文件、VRML文件和Wavefront文件类型，或者是ASCII文件类型。我们使用的数据布局在这个时候扩展到了许多文件类型。但STL文件是从工业现场标准化的关系到激光手持树脂复制系统输出文件中的标准数据布局，在X射线CT扫描仪的图像数据中，DICOM3实际上是一个国际标准。认为DICOM3的图像数据附加为另一文件的坐标轴数据用于三维数据分析的方法在与用于诊断的医疗图像的互换性方面是优秀的。牙模信息的图像数据是有利的文件格式，是原始数据文件格式(DNT：UNISN Co.Ltd.)。由于单面模型只有500KB，采用这种DNT文件格式有利于文件的大小和数据的网络传输。模型数据的显示和测量是与UNISN公司合作在Microsoft Windows系统上新开发的应用程序软件。其中涉及到牙科模型三维数据的处理。

Basic data of the three-demensional analysis as for the preservation form of a three-dimensional image, the applied field like the voxel model, the surface model (solid model), and the resin replica model, etc. separates into many topics. It was thought that the standardizaion of the file format which contained all those image informations was impossible.The preservation of the voxel model by the geometry file was excellent. The surface model (solid model) was DXF file, VRML file, and a wavefront file type or, it was ascii file type. Data layout which we had used extended to many file type in this time. But STL file is from a relation standardized in an industrial field to standard data layout in the file for the laser handed resin replica system output.In the image data of X-ray CT scanner, DICOM3 was an intemational standard in fact. It was thought that the method of the shape added to the image data of the DICOM3 from appending as another file of the data of coordinate axis, which was used at the three-dimensional data analysis, was excellent in respect of interchangeability with the medical treatment image for the diagnosis.The image data of the information of dental cast model was advantageous file format, which was an original data file form (DNT : UNISN Co.Ltd.). This DNT file format was used to be advantageous of the dosage of the file and I thought the data transfer in which the network, because the one side dental cast model was only 500KB.The application program software, that the display and the measurement of the dental cast model data, are newly developed on the Microsoft Windows System by the cooperation of UNISN Co.Ltd. Which are concerning the processing of the three-dimensional data of the dental cast model.
