Mapping of Cumulative Meterset (300A,063C) to Radiation Dose Value (300A,0625).
This may be as defined in the RT Radiation Set for the RT Radiation or calculated for this RT Radiation Record Set.
See Section C.36.11.1.1.
Two or more Items shall be included in this Sequence.
Section C.36.11.1.1
C.36.11.1.1 Meterset to Dose Mapping Sequence
The Meterset to Dose Mapping Sequence (300A,0620) contains for each Meterset value the corresponding dose value.
In the first item, the value of Cumulative Meterset (300A,063C) and of Radiation Dose Value (300A,0625) shall be zero.
In the last item, the value of Cumulative Meterset (300A,063C) shall be the Meterset of the final Control Point. The value of Radiation Dose Value (300A,0625) in the last item represents the dose delivered to the referenced anatomy when one fraction is completely delivered.
Cumulative Meterset Values shall be strictly monotonically increasing. Radiation Dose Values shall be monotonically non-decreasing. The increase of dose between two adjacent points of the lookup table shall be interpreted as linear.
