KeywordDefinitionSourceSequence
Value Multiplicity1
Value RepresentationSequence (SQ)

Instances containing the source of the ROI Contour information.

Only a single Item is permitted in this Sequence.

Permitted Referenced SOP Classes are defined in Section C.36.2.1.6.1.4.

See Section C.8.8.13.2.

Section C.36.2.1.6.1.4

C.36.2.1.6.1.4 Referenced Attribute Number

The referenced SOP Classes permitted in the Definition Source Sequence (0008,1156) are listed in Table C.36.2.1.6-2.

For each referenced SOP Class, the Referenced Beam Number (300C,0006) in the Definition Source Sequence (0008,1156) identifies an Item in a specific Sequence in the referenced Instance by specifying a number that matches the value of an Attribute contained in that Sequence as defined in Table C.36.2.1.6-2.

Section C.8.8.13.2

C.8.8.13.2 Definition Source Sequence

The Definition Source Sequence (0008,1156) references SOP Instances of First or Second Generation Radiotherapy IODs as the source of the information which has been transcoded to the current SOP Instance up to the capability of the current SOP Class. The Definition Source Sequence shall not be used when the current SOP Instance represents a derivation or successor of the source Instance. The source Instance shall not contain a reference to the current Instance.

Typical use cases are: A device (e.g. a treatment planning system or treatment delivery system) is creating Second Generation SOP Instances and additionally encoding them in First Generation SOP Instances for other receivers supporting First Generation RT IODs only. Another use case is that an application receives Second Generation SOP Instances and transcodes them to First Generation SOP Instances to make the content available to receivers supporting First Generation IODs only.

The same applies for the reverse use cases when the source Instance is a First Generation SOP Instance and the current SOP Instance is a transcoded Second Generation SOP Instance.
