DICOM图象显示的研究与实现

DICOM是用于医学图象和通信的国际标准 ,它规范了医学图象及各种数字信息在异构系统和设备之间存储、传送时的文件格式和语义描述。本文首先针对DICOM 3.0标准 ,系统地分析了DI COM对象关系文件格式 ,主要阐述了数据元和数据集的格式 ,重点介绍了象素数据元的格式 ;然后提出了一个在Windows平台下显示DICOM图象的简化的图象类结构 ,并简要描述了数据元操作和图象处理的成员函数 ;最后介绍了软件各功能模块 ,着重介绍了图象显示变换模块的实现过程

Research and Implementation of DICOM Image Displaying

DICOM is an international standard in medical imaging and communications. It defines the rules of pixel data and other digital information when they are transferred or stored between devices with different operating systems or of different manufacturers. This paper first introduces the DICOM file format, including the structures of data elements and pixel data elements, and then presents a reduced class of DICOM images and introduces its member functions. Finally it introduces the software modules and emphasizes the implementation of the image displaying and transforming module.
