About

dcm_qa_deident is a simple DICOM to NIfTI validator script and dataset. This repository is similar to dcm_qa, but validates the detection of [https://github.com/bids-standard/bids-specification/issues/1709](deidentification methods) that have now been added to the BIDS format.

Looking at a DICOM header with dcmdump or gdcmdump will reveal that the DICOM images have de-identification details that can be preserved:
