JPEG2000压缩DICOM文件的解压（一）

JPEG2000压缩DICOM文件的解压（一）

    这几天写了一个JPEG2000压缩DICOM解压的下程序

    DICOM文件中如果标签如下：

     0002,0010里的值为    1.2.840.10008.1.2.4.90  或 1.2.840.10008.1.2.4.91  则该文件是 jpeg 2000 编码

    开源的DICOM软件包中，DCMTK是非常优秀的软件包，但该软件包关于JPEG2000解压或压缩的部分是收费的，

     所以就想自己写一个关JPEG2000解压的小程序。

     一下是采用DCMTK，将JPEG2000压缩的DICOM文件转换为XML文件的截图，可以看到所有的标签。
