使用DCMTK实现DICOM文件浏览器dicom explorer

之前一直使用别人的免费浏览工具来浏览DCM图像，或多或少都存在小的问题，要么完全免费但是功能不全不好用，要么就是收费需要定期下载版本申请试用，折腾来折腾去很是费心，决定最近自己写个简单的，不求功能强大只求自己用起来得心应手。

底层文件的读取使用DCMTK3.6.3的DCMData包；考虑支持跨平台，上层显示使用QT来做。

 在Linux和windows两个平台下编译DCMTK生成的Config文件夹中的头文件内容是不同的，为了更好地组织两个平台的头文件和库文件，在dcmtk文件夹分别新建linux和win文件夹，将ubuntu下编译后的include文件夹拷贝到linux下，将win7下编译后的include文件夹拷贝到win下。读取文件主要使用DCMTK的DcmData库，该库依赖了ofstd,oflog库，为了支持RLE压缩和JPEG压缩，还需要dcmjpeg库。以linux为例，将编译后的config文件夹下的include目录和源码中的ofstd,oflog,dcmjpeg,dcmdata文件夹中的include文件夹拷贝到dcmtk/linux/include目录下，并在工程文件.pro中将这些目录添加到INCLUDEPATH中；
