- Specific use cases and requirements for de-identification
- Requirements
- 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
- Requirements
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)
- Usecases
