Relative dose export with DICOM Export script

By default the RD files that are exported using the DICOM export script provided on this website are Relative.
In their DICOM tag 3004,0002 "DoseUnits" it has Relative.

I tried the following before generating the dcmtk export script:
verificationPlan.DoseValuePresentation = DoseValuePresentation.Relative;

But it doesn't seem to work.

Any ideas how to get Absolute dose via DCMTK movescu ?

Thanks

The Dicom daemon only supports relative dose export in version 13.0 and earlier. It has been changed to always export absolute dose in the upcoming 13.5 release.

In the meantime, you would have to manually convert the values. To get absolute dose for plan dose, multiply the relative values by dPrescribedDosePerFraction * nFractions / dTreatmentPercentage. For beam dose, multiply by dPlanNormFactor * dPrescribedDosePerFraction * nFractions / dTreatmentPercentage.

These values can be received from API:
  PlanSetup.PrescribedPercentage;
  PlanSetup.UniqueFractionation.PrescribedDosePerFraction;
  PlanSetup.UniqueFractionation.NumberOfFractions;
  PlanSetup.PlanNormalizationValue;
