DICOM de-identification tool overview

Home < DICOM de-identification tool overview

Specific use cases and requirements for de-identification

Client side processing
Offline processing
Platform and browser independent
Provided as commandline tool?
In-application processing should be possible?
- e.g. in MITK and Slicer?
Specify conditions like if tag value is equal to XYZ then remove all private tags except of <tag list>

Some issues, which anonymization tools often have, found on the Plastimatch homepage, also providing a comparison:

Some date fields cannot be changed (duh)
It is not possible to preserve relative dates (for example, we would like to set StudyDate to Jan 1, 2000, but preserve the fact that StructureSetDate occurred 35 days later)
Private tags are always deleted (on our GE scanner, these contain important acquisition details)
Comments, diagnosis descriptions, or other fields cannot be reset (may contain protected information)
It is not possible to modify strings (for example, the physician might type “smith-final” into the StructureSetName field, and we would like to delete “smith” but preserve “final” )
UIDs are not changed, or relationships between UIDs are not preserved (duh)
