OnkoDICOM takes your identified DICOM-RT dataset and produces a new identifier which cannot be tracked back to the patient's name. The new identifier acts like a fingerprint and is saved within OnkoDICOM along with the old patient identifier. Keeping this spreadsheet secure is the user's responsibility.
The anonymisation process is built into a batch process that anonymises the DICOM files first and then produces three anonymised spreadsheet files. OnkoDICOM is the only produce to give this level of anonymisation.
