procedure IEAnonymizeDicomTags(DICOMTags: TIEDicomTags; const AnonymizeStr: string = 'Anonymous);Description
Removes all personally identifiable information from the tags of a DICOM file.For any personal tags that are found: String values will be set to AnonymizeStr. Numeric values will be set to 0 and data values will be deleted.
Identifiable tags are defined by:
http://dicom.nema.org/dicom/2013/output/chtml/part15/chapter_E.html#table_E.1-1
A more precise anonymization strategy would follow the specific methods described in this document. You can access the recommended anonymization method using IEDicomGetTagInfoEx.
Note:
◼ The anonymity provided by this method is not guaranteed. Ensure you fully validate your files after usage
◼ This method does not strip any private attributes
◼ You cannot anonymize tag-only dicom files
◼ ieDicomTags adds about 400KB to your exe

Example
// Create an anonymous version of a dicom fileImageEnView1.IO.LoadFromFile( OpenImageEnDialog1.FileName );
if ImageEnView1.IO.Params.FileType = ioDICOM then
begin
IEAnonymizeDicomTags( ImageEnView1.IO.Params.DICOM_Tags );
destFN := ChangeFileExt( ImageEnView1.IO.Params.FileName, '-Anonymous.dicom' );
ImageEnView1.IO.InjectDICOMTags( ImageEnView1.IO.Params.FileName, destFN );
