# **1.        前言：** #

基于DICOM3.0标准的医学图像中，每一张图像中都携带着许多的信息，这些信息主要可以分为Patient, Study, Series和Image四类。每一个DICOM Tag都是由两个十六进制数的组合来确定的，分别为Group和Element。如(0010,0010)这个Tag表示的是Patient’s Name，它存储着这张DICOM图像的患者姓名。

在研发关于医学影像软件时，必然需要对导入的DICOM图像进行文件解析，很重要的一部分工作就是需要从图像中获取它所储存的信息，然后在开发的软件中根据需要显示出来。一般医学影像软件在显示某一张影像时会有四角信息，或者当医生在调整窗宽窗位值时，需要软件实时显示此时的值。

基于C++的DCMTK和基于Java的dcm4che，都是非常优秀的解释DICOM标准的第三方库，通过在工程中引入它们可以避免软件开发人员去进行底层的解析工作，可为项目开发提高效率。

以下是归纳的常见的DICOM Tag标签，和它们的描述和值表现(VR)。

# **2.        VR** #

VR是DICOM标准中用来描述数据类型的，总共有27个值。简单分类如下：
