Technical note

NII to PS: what carries over and what does not

The standard NII header has no fields for a patient's name, birth date or accession number, only an 80-character free-text description, which is one reason research pipelines convert DICOM to NIfTI before data is shared. That does not make every output anonymous. A head scan contains the face, and a 3D rendering of the volume can reconstruct it well enough to recognise someone, which is why public datasets are usually defaced first. Slices that pass through the front of the head carry the same risk. PS is a page format, so each NII image is placed on a page rather than converted into something else. Two settings decide how the result looks: the DPI, which fixes how large the image sits on the page, and whether a batch becomes one file per image or a single merged document. reaConverter can do either.

Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch.
