DICOM De-identification Workload Calculator accuracy and testing

Formula source

• Total hours = (studies x instances per study x processing seconds / 3600 + studies x review minutes / 60) x (1 + rework percent / 100). Workdays = total hours / staff hours per day.

Test cases

Known limitations

• This page documents the checked-in calculator logic and does not certify results for every real-world edge case.
• Use the result as a planning estimate unless the calculator page states a stricter purpose.

Assumptions

• The calculators use transparent formulas rather than vendor-specific sizing or compliance models.
• Inputs are processed locally in the browser and are not stored by Calwarden.
• De-identification can be privacy- and research-governance-sensitive; validate methods, tags, burned-in annotations, and release rules before sharing data.

• Instances per Study accepts numeric values.
• Processing Time per Instance accepts values in sec.
• Review Time per Study accepts values in min.
