A.1.2.18 Surface IE​

The Surface IE defines the Attributes that describe a surface in a spatial coordinate system. A surface is defined by its shape and​ can be further defined by normals on that shape. The surface may be reconstructed from either spatial scans (e.g., laser scanners)​ or based on images. A surface is described by its finite volume and manifold property, gray scale and color mapping characteristics,​ presentation type, opacity, and modality specific characteristics.​

A surface is related to a single Series.​

A.1.2.19 Measurements IE​

The Measurements IE defines the Attributes that describe the measurements taken by medical instruments.​

A.1.2.20 Tractography Results IE​

The Tractography Results IE defines the Attributes that describe the results of a tractography application.​

Note​

The term tractogram is not used because it does not include all types of tractography results.​

A.1.2.21 Plan IE​

The Plan IE defines the parameters and instructions to deliver treatment, particularly Radiotherapy, to the Patient. The entity includes​ thesetofmachineandpositioningparameterstobeappliedduringtreatmentdeliveryandinstructionsguidingthetreatmentworkflow.​

A.1.2.22 Content Assessment Result IE​

The Content Assessment Result IE contains the results of an assessment of the content of a SOP instance.​

An assessment is part of a process within a clinical workflow, conducted by users or devices, which have the role of assessing the​ validity and suitability of the content in question, based on subjective or objective criteria. The specific nature of such a process is​ outside of the scope of this Standard.​

A.1.2.23 Spatial Fiducials IE​

The Spatial Fiducials IE identifies one or more geometric locations or shapes within a Frame of Reference or image pixel/voxel space​ that may be correlated with similar locations or shapes within different frames of reference or image pixel/voxel spaces.​

A.1.2.24 Dose IE​

The Dose IE describes dose distributions calculated by radiotherapy treatment planning systems. These distributions may be repres-​ ented as 2D or 3D grids, as isodose curves, or as named or unnamed dose points scattered throughout a volume.​

A.1.2.25 Structure Set IE​

The Structure Set IE describes Regions of Interest (ROI) within a referenced 2D (image) or 3D (volumetric) space. These ROIs may​ be represented as geometric contours.​

A.1.2.26 Treatment Record IE​

The Treatment Record IE describes treatments, particularly radiotherapy, for a Patient.​

A.1.2.27 Stereometric Relationship IE​

The Stereometric Relationship IE defines how referenced images are related as stereometric pairs.​

A.1.2.28 Procedure Protocol IE​

The Procedure Protocol IE defines the Attributes that describe a Protocol. This IE may encode a Defined Procedure Protocol or a​ Performed Procedure Protocol.​

A.1.3 IOD Module Table and Functional Group Macro Table​

This Section of each IOD defines in a tabular form the Modules comprising the IOD. The following information must be specified for​ each Module in the table:​

•​The name of the Module or Functional Group​

•​A reference to the Section in Annex C that defines the Module or Functional Group​

•​The usage of the Module or Functional Group; whether it is:​

•​Mandatory (see Section A.1.3.1), abbreviated M​

•​Conditional (see Section A.1.3.2), abbreviated C​

•​User Option (see Section A.1.3.3), abbreviated U​

The Modules referenced are defined in Annex C.​

A.1.3.1 Mandatory Modules​

For each IOD, Mandatory Modules shall be supported per the definitions, semantics and requirements defined in Annex C.​

A.1.3.2 Conditional Modules​

Conditional Modules are Mandatory Modules if specific conditions are met. If the specified conditions are not met, this Module shall​ not be supported; that is, no information defined in that Module shall be present.​

A.1.3.3 User Option Modules​

User Option Modules may or may not be supported. If an optional Module is supported, the Attribute Types specified in the Modules​ in Annex C shall be supported.​

A.1.4 Overview of the Composite IOD Module Content​

The Tables in this Section provide an overview of the Modules used throughout the Composite IODs. This table is for informative​ purposes only. It is based on the IOD definitions found in the remaining Sections of Annex A that are normative.​

Note​

1.​The original US Image IOD and US multi-frame IOD, and the associated US and US multi-frame Storage SOP Class​ UID have been retired. New US and US multi-frame Image IODs are defined, as shown in Table A.1-1a, which includes​ the Palette Color Lookup Table Module.​

2.​The original NM Image IOD and the associated NM Storage SOP Class UID have been retired. A completely new NM​ Image IOD is defined, as shown in Table A.1-1a.​
