Outlined the system ' s structure and organization combining the data structure , alternating actions between the user and the system and the system ' s data process function . adopted the object oriented design method to construct the object model of the solution space around the problem domain sub - system and the alternating sub - system of the user and the computer . the design of the programs realized the construction and package of core classes and basic operations such as read , write and change dicom files based on the dicom file services 结合系统数据结构、用户与系统交互行为和系统数据处理功能，概要设计了系统的组织和结构；采用面向对象的设计方法，围绕问题域子系统和人机交互了系统，建立了求解空间的对象模型；程序设计围绕dicom文件服务功能，实现了核心类的构造和封装以及dicom文件的读、写、修改等基本操作。
