使用DCMTK库实现BMP转DCM的互相转换以及JPEG转DCM。使用DCMTK库其中在编译的时候错了好几次，在这有编译好的库给大家分享在此附上连接只需要1积分(https://download.csdn.net/download/qq_37529913/10793075)。直接使用DCMTK库实现的功能，期间本人也下载了好多但是大部分都没用复制粘贴出来的水贴有点多。其中借鉴了zssure大神的两篇文章(JPEGhttps://blog.csdn.net/zssureqh/article/details/42200303/)(BMPhttps://blog.csdn.net/zssureqh/article/details/42119303)zussre大神在贴中介绍了包括BMP、JPG结构和需要引入的一些文件，我在这再给大家介绍一些Dcm常用的Tag属性值(https://blog.csdn.net/wenzhi20102321/article/details/75127362)很感谢峥嵘life大佬，这里再给大家附上一个全的dcm的Tag(https://sno.phy.queensu.ca/~phil/exiftool/TagNames/DICOM.html)属于DICOM官方给出的标签很实用虽然没有详解。

使用VC++，MFC实现了Bmp和JPG的相互转换，JPEG转DCM图。包括dcm图Tag值的讲解以及实现。

代码实例：

DCMTK库的使用(使用VS大部分版本属性设置都是一样的)

VS2017项目->属性->

包含目录填DCMTK库的include目录(X:\dcmtk库\include\)

 PS：以上是三种转换方式楼主亲测，虽然补了很多漏洞，毕竟努力了好久了完整版的就不发出来了，把大概的实现发出来了。AddDicomElements((DcmDataset*&)mydatasete);这个删掉就好缺什么字段在后面使用mydatasete->这个添加就好，有三四处内存泄漏需要各位小伙伴自己找一下，dcmtk的标准还有一些字段的意思还得大家自己去研究，按照这个改一改完整版的完全可以做出来，有什么问题可以留言，看到会及时回复的。(如果对你有帮助记得点赞关注在走哦)
