Abstract: Described in this paper are the data structure and encoding rules of digital imaging and communication in medicine radiotherapy in tumor radiation therapy. The process and the actual distribution of the radiation data integrated. Expanded the relevant issues of data base standardization construction, focus on the logical relationship of data analysis and the details of the data construction process, combined the data processing in clinic with the method of software technology in data analysis, further explore the issues related to data integration and application in radiation therapy.
