Abstract: DICONDE as an international standard for digital imaging and communications in Nondestructive Evaluation, the construction and generation of its file is basis of generalizing the standard and the relative research was carried out based on DCMTK. Firstly, based on careful analysis of the information model of DICONDE, the constructing procedure of DICONDE was given. Then, taking the storage system of digital X-ray image as example, the developing environment based on DCMTK was set up and the detailed developing procedure was given. At last, the generated files were tested by professional software. The result showed that the generated files could be identified as DICONDE file, and the image and other information in the files were read correctly. In addtion, it also supported Chinese. Besides, the way based on DCMTK was easier to develop and had some practical value.
