Typical usage

Copy Attribute Value to file

This will extract the value at Tag (0025,101b):

$ gdcmraw -i GE_MR_0025xx1bProtocolDataBlock.dcm -t 25,101b -o pdb.raw

Extract Pixel Data

If you do not specify any tag, the Pixel Data element is the default one. So for instance to grab the Pixel Data from an image:

$ gdcmraw -i test.acr -o test.raw 

You can then for example compute the md5sum of this pixel data (very useful):

$ md5sum test.raw
f845c8f283d39a0204c325654493ba53  test.raw

Encapsulated Syntax

When the Pixel Data is encapsulated, multiple fragments can be used to store a single slice image:

$ gdcmdump D_CLUNIE_CT1_J2KR.dcm
