DICOM Tag Search accuracy and testing
This page documents how Calwarden builds trust for this calculator: source notes, regression-style default tests, limitations, assumptions, unit handling, rounding, and visible change history.
Formula source
- DICOM tags are identified by a Group number and an Element number (GGGG,EEEE) in hexadecimal. Each tag also has a Value Representation (VR) which dictates the data type (e.g., DA for Date, PN for Person Name).
Test cases
Default input regression check
Generated from the checked-in default inputs and calculate function.
Inputs
- Search Tag or Name:

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 search covers a curated set of commonly encountered tags rather than the full DICOM dictionary.
- Private tags, retired elements, and vendor-specific encodings may not appear here.
- This lookup is intended for orientation and troubleshooting, not for replacing the official DICOM standard.
Unit handling
- Search Tag or Name accepts text values.
Rounding rules
- Number displays use up to 2 decimal places in the calculator UI.
