Résumé

Complex Extension: Dose To Volume

- volume: Reference: The volume targeted by the dose.
- fractionDose: string: Expected radiation dose per fraction. The division numberOfFractions/totalDose must be done
- numberOfFractions: unsignedInt: Number of fractions expected. Dicom Tag (300A,0078).
- totalDose: string: The total amount of radiation delivered to this volume. Dicom Tag (300A, 0026). If delivred, it should be extracted from MOSAIQ/ARIA Record and Verify
- rtDoseUID: string: Reference SOP Instance UID of the RT Plan
