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

三维分析的基础数据作为三维图像的保存形式，其应用领域如体素模型、曲面模型（实体模型）、树脂复刻模型等分为多个主题。有人认为，要使包含所有这些图像资料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）为DXF文件，VRML文件，波前文件类型或为ascii文件类型。我们以前使用的数据布局在这次扩展到许多文件类型。而STL文件则是从工业领域中标准化的一种关系，转变为激光手工树脂复制系统输出的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实际上是国际标准。认为在三维数据分析中采用的将坐标轴数据作为另一文件追加到DICOM3图像数据中的形状添加方法，在与医学治疗图像的互换性方面具有很好的互换性。牙铸模型信息的图像数据为优势文件格式，为原始数据文件形式（DNT: UNISN Co.Ltd.）。这种DNT文件格式被用来是有利的文件的用量和我认为数据传输在其中的网络，因为一侧牙铸模型只有500KB。在Microsoft Windows操作系统上，与UNISN公司合作开发了牙铸模型数据显示和测量的应用程序软件。这些都涉及到牙科铸型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.
