The RT Treatment Phase which is related to the phase identified by Basis RT Treatment Phase Index (3010,003E). Each RT Treatment Phase Index value shall appear in this Attribute in only one Item within this Sequence.
This index corresponds to an Item in the Intended RT Treatment Phase Sequence (3010,004B).
See Section C.36.2.1.3.1.

The RT Treatment Phase Interval Sequence (3010,004E) allows the definition of an interval between two treatment phases. RT Treatment Phases referenced by the Basis RT Treatment Phase Index (3010,003E) and the Related RT Treatment Phase Index (3010,003F) are related in terms of the number of days between them. Note that the number of days can also be negative and therefore the related treatment phase could start before the prior treatment phase starts respectively ends.
Each RT Treatment Phase identified by the Related RT Treatment Phase Index (3010,003F) may be related to only one RT Treatment Phase identified by the Basis RT Treatment Phase Index (3010,003E). Therefore, any Basis RT Treatment Phase Index (3010,003E) must only appear once in Related RT Treatment Phase Index (3010,003F) within the Sequence.
See also Section C.36.6.1.4.
As a result of the combinations possible, the maximum number of Items in the RT Treatment Phase Interval Sequence (3010,004E) shall be one less than the number of treatment phases present.
