The Volume Rendering Volumetric Presentation State IOD is used in three SOP Classes as defined in PS3.4:​ •​one SOP Class allowing a single input volume and excluding segmentation cropping​

•​one SOP Class allowing a single input volume with multiple input segmentations each with a distinct classification map​ •​one SOP Class allowing multiple input volumes, segmentations, and classification maps​

A.80.2.2 Volume Rendering Volumetric Presentation State IOD Entity-Relationship​

Model​

This IOD uses the E-R Model in Section A.1.2, with only the Presentation State IE below the Series IE.​

A.80.2.4 Volume Rendering Volumetric Presentation State IOD Content Constraints​

A.80.2.4.1 Presentation Input Restrictions​

Presentation Input Type (0070,1202) shall have a value of VOLUME.​

See Section B.5.1.24 “Volume Rendering Volumetric Presentation State Storage SOP Classes” in PS3.4 for SOP Class-specific​ Presentation Input Restrictions.​

A.80.2.4.2 Graphic Annotation Module​

The values of the following Attributes, if present, shall be DISPLAY:​

•​Bounding Box Annotation Units (0070,0003)​

•​Anchor Point Annotation Units (0070,0004)​

•​Graphic Annotation Units (0070,0005)​

•​Compound Graphics Units (0070,0282)​

Note​

The specified annotation is associated with the specified View and not with the input data, and may have clinical relevance​ only to the specified View. Therefore, if an application alters the View from that defined by the Presentation State, annotation​ may no longer be clinically correct.​

A.80.2.4.3 Render Shading Module​

If the Render Shading Module is omitted for a rendered view, an unshaded volume rendering shall be performed.​

A.80.2.4.4 Volumetric Presentation State Reference Coordinate System​

All SOP Instances referenced in the Volumetric Presentation State Relationship Module shall be registered to the Volumetric​ Presentation State Reference Coordinate System. See C.11.23.3.​

A.81 Content Assessment Results IOD​

A.81.1 Content Assessment Results IOD Description​

This IOD represents the results of an assessment of the content of one or more SOP Instance(s). The assessment may be performed​ automatically without human intervention. There is no provision for encoding verification or approval by a human, although a human​ maybeinvolvedindeterminingwhetherthecontentsmeetcertaincriteria.ThisIODisnotintendedtocommunicateapprovaltoproceed​ with the clinical workflow.​

The Content Assessment Results SOP Instance is not required to be part of the same Study as the assessed SOP Instances.​

A.81.2 Content Assessment Results IOD Entity-Relationship Model​

The Content Assessment Results IOD uses the E-R Model in A.1.2, with only the Content Assessment Results IE below the Series​ IE. The Frame of Reference IE is not a component of this IOD.​

A.81.3 Content Assessment Results IOD Module Table​

A.81.4.1 Modality​

The value of Modality (0008,0060) shall be ASMT.​

A.82 Procedure Protocol Information Object Definitions​

Procedure Protocol Information Object Definitions (IODs) encode the details of procedure protocols.​

SeparateIODsaredefinedfordifferenttypesofProcedureProtocol,suchasaCTimageacquistionProcedureProtocol.ACTPerformed​ Procedure Protocol IOD encodes the details of a procedure that has been performed, and a CT Defined Procedure Protocol IOD​ specifies details of a procedure that may be used for one or more Procedure Protocols to be peformed in the future.​
