Sanitarization of headers/filenames¶
- see http://www.researchgate.net/post/Best_free_tool_for_DICOM_data_anonymization discussion on sanitarization of DICOM headers
- DeID (see paper), which provides an interactive tool for inspection and sanitarization of Analyze and NIfTI images
Elimination of facial (and dental) features¶
One of the approaches is perform complete skull stripping using the used analysis toolkit, e.g.
Some dedicated annonimization tools work on this principle, e.g. DeID
More “gentle” approach is to strip out only the areas of face/mouth leaving skull, which might be important for some types of analysis. Usually achieved through alignment of pre-crafted mask to the subject anatomy and removing of the masked out regions.
Rendering faces unrecognizable¶
Even more data/information preserving approach is to just obscure facial features in the anatomical images:
