C.8.8.5.1 Frames of Reference

The Referenced Frame of Reference Sequence (3006,0010) describes a set of frames of reference in which some or all of the ROIs are expressed. Since the Referenced Frame of Reference UID (3006,0024) is required for each ROI, each Frame of Reference used to express the coordinates of an ROI shall be listed in the Referenced Frame of Reference Sequence (3006,0010) once and only once.

Note

As an example, a set of ROIs defined using a single image Series would list the image Series in a single Referenced Frame of Reference Sequence (3006,0010) Item, providing the UID for this referenced Frame of Reference (obtained from the source images), and listing all pertinent images in the Contour Image Sequence (3006,0016).

C.8.8.5.2 Frame of Reference Relationship Sequence and Transformation Matrix (Retired)

Retired. See PS3.3-2011.

Note

The concept of definition of registered Frame of References using the Frame of Reference Relationship Sequence (3006,00C0) formerly present in the Standard is retired. The use of Registration IODs is advised since the introduction of Spatial Registration IOD, which is a much stronger and more general concept, and independent from the specifics of RT Structure Sets. Additionally it is of importance that registrations are decoupled from image and segmentation objects.

C.8.8.5.3 ROI Derivation Sequence

If an ROI is created by re-sampling an existing ROI that is either (a) present in a different Frame of Reference (FoR) and has been resampled to align with the image Series referenced by the current structure set, or (b) present in the same FoR, but its contours are referenced to a different image Series, it is useful to be able to identify that the ROI is resampled. The Derivation Code Sequence (0008,9215) shall be used with code (113085, DCM, "Spatial resampling") to indicate the resampled ROI.

C.8.8.5.4 SOP Class UID in RT Referenced Study Sequence

Since RT Referenced Study Sequence (3006,0012) is Type 3, the Attribute may be omitted.

If RT Referenced Study Sequence (3006,0012) is present with an Item, for each Item, the SOP Class UID is that of the Study itself, not of the Instances within the Study. The Detached Study Management SOP Class (Retired) ("1.2.840.10008.3.1.2.3.1") may be used in Referenced SOP Class UID (0008,1150) in lieu of there being any other private or standard Study SOP Class defined.

Note

The SOP Class of an Instance (e.g., of one of the images within the referenced Study) is not used, even if all of the Instances within the Study are of the same Instance SOP Class.

  1. The Audio Module (Retired) was previously included in this IOD but has been retired. See PS3.3-2004.

  2. Previously the Frame of Reference Module was not included (see PS3.3-2014b). Historically, more than one Frame of Reference could be referenced within the Structure Set Module's Referenced Frame of Reference Sequence (3006,0010), in which case the Frame of Reference Module would not have been present.

Note

Treatment Date (3008,0250) and Treatment Time (3008,0251) can be used to chronologically order a sequence of treatments, where each treatment is represented by an Instance of a RT Beams Treatment Record or RT Brachy Treatment Record. In the case of a RT Treatment Summary Record, it can be used to identify the period for which the treatment summary is valid. Therefore, implementers are strongly advised to include values for these Attributes whenever possible.
