I think there was an anonymization tool developed through the BIRN and distributed by Ron Kikinis' group at the BWH. I'll cc Karl Helmer who probably knows

Hi Freesurfer Experts, we are looking for a good way to remove subject names and dates of birth from Siemens DICOM headers. Is there something implemented in Freesurfer?

Matlab's Image Processing Toolbox has a function to anonymize DICOM files (http://www.mathworks.com/help/images/ref/dicomanon.html), but we later run into trouble with unpacksdcmdir when we use that.

Thanks, Caspar

Hi Caspar, I can't address your question regarding a specific tool, but wanted to mention a note of caution. You need to make sure that you scrub any identifying info from Siemen's custom DICOM fields (not just the obvious public DICOM fields). The challenge of doing that is why the safest thing is to not enter any identifying info at the scanner to begin with.

You could also do it the following way: (you need to download dcmtk) Assuming you have a bunch of files called MR.*

for dicom in MR.* do dcmodify -m "(0010,0010)=PatientsName" ${dicom} dcmodify -m "(0010,0030)=YYYYMMDD" ${dicom} done

This backs up all the dicoms (they become "MR.*.bak"), which you can delete when you verify the new header. Replace "PatientsName" with whatever you want. However, as Michael Harms mentioned there may be identifying info elsewhere in the file.
