RE: Customizing dicom header

Justin,


When you use the DICOM-based workflow, it does NOT assign new UIDs for study and series instance UID (copies them verbatim), but it DOES add 113102 "Clean Recognizable Visual Features Option" to DeidentificationMethodCodeSequence. SOPInstanceUID and MediaStorageSOPInstanceUID are assignesd a new UID, however. I based this on the idea that it's new DICOM files, but it's still the original study and series. We also assume that this would typically be used in tandem with some other DICOM deidentification suite, which would typically assign new Study and Series UIDs while de-identifying other DICOM tags, so having our software change them would be redundant in most reasonable workflows.

Hi Chris,


When you process DICOM data do you generate unique UIDs for things like Series Instance UID and SOP Instance UID?  Or are those directly copied from the original data?  In general, I think for our purposes we'd want all relevant UIDs to be new ones that uniquely distinguish this modified series from the original.  


Also, do you populate the De-identification Method Code Sequence to indicate the Clean Recognizable Visual Features Option has been applied?


Thanks,


Justin
