Table C.36.9-1 specifies the Attributes of the Segment Reference Module, which reference geometrical representations, such as regions of interest, surfaces, lines, or points, which have been associated with a Conceptual Volume.
These referenced representations are referred to as segments.

One or more Items shall be included in this Sequence. See Section C.36.9.1.3. |

Directly identifies a specific segment in a specific SOP Instance. Required if Combination Segment Reference Sequence (3010,0024) is not present. Only a single Item shall be included in this Sequence. See Section C.36.9.1.3. |

Segment Number (0062,0004) in the referenced SOP Instance. Required as described in Section C.36.9.1.1. |

|
Fiducials UID (0070,031A) in the referenced SOP Instance. Required as described in Section C.36.9.1.1. See Section C.36.9.1.1. |

ROI Number (3006,0022) in the referenced SOP Instance. Required as described in Section C.36.9.1.1. See Section C.36.9.1.1. |

|
Surface Number (0066,0003) in the referenced SOP Instance. Required as described in Section C.36.9.1.1. See Section C.36.9.1.1. |
|||
|
Defines a segment as a combination of other segment Items present in the Segment Reference Sequence (3010,0021). Required if the Direct Segment Reference Sequence (3010,0023) is not present. Only a single Item shall be included in this Sequence. See Section C.36.9.1.3. |

Sequence defining the general category of the property the segment combination represents. |

Sequence defining the modifier of the property type the segment combination represents. Required if Segmented Property Category Code Sequence (0062,0003) has a value. |

Registrations between Frames of Reference of Instances referenced in the Referenced SOP Sequence (0008,1199) in the Direct Segment Reference Sequence (3010,0023). Required if any Item in the Combination Segment Reference Sequence (3010,0024) combines segments that do not have the same Frame of Reference UID (0020,0052). |

Only the SOP Classes contained in Table C.36.9-2 shall be referenced.
The column Referenced Attribute identifies the Attribute used to identify the geometric representation in the SOP Instance referenced in the Segmentation Referenced SOP Sequence (0008,1199).
Depending on the SOP Class UID (0008,0016) in the Referenced SOP Sequence (0008,1199) the corresponding Attribute as specified in the Required Referencing Attribute column is required to be present.
It is anticipated that in future additional referencing Attributes may be needed to accommodate new representations of segmentations. Hence the collection of Required Referencing Attributes in Table C.36.9-1 Segment Reference Module Attributes and the conditionally required Type 1C Attributes in the Segment Reference Module may be extended.
A Conceptual Volume may be expressed as a combination of other segmented Conceptual Volumes. Those other segments are referenced in the Section 10.34 Conceptual Volume Segmentation Reference and Combination Macro.
The Conceptual Volume Combination Flag (3010,000E) shall be YES. The Conceptual Volume Segmentation Defined Flag (3010,0010) shall be NO. The Conceptual Volume Constituent Segmentation Reference Sequence (3010,0012) in the Conceptual Volume Constituent Sequence (3010,0008) shall not be present since the segmented representation of a constituent of a combination is specified by an Item of the Segment Reference Sequence (3010,0021) as follows: If a constituent in the Conceptual Volume Constituent Sequence (3010,0008) is a combination its constituents must
All Conceptual Volume References in this Macro shall reference only segments that are defined in Items in the Direct Segment Reference Sequence (3010,0023).
