### A.80.1 Planar MPR Volumetric Presentation State IOD

#### A.80.1.1 Planar MPR Volumetric Presentation State IOD Description

The Planar MPR Volumetric Presentation State Information Object Definition (IOD) specifies information that defines a Planar MPR presentation from volume datasets that are referenced from within the IOD.

It includes capabilities for specifying:

1. spatial registration of the input datasets

2. cropping of the volume datasets by a bounding box, oblique planes and segmentation objects

3. the generation geometry of thin and slab Multi-Planar Reconstructions

4. the method for rendering slab Multi-Planar Reconstructions

5. scalar to P-Value or RGB Value conversions

6. compositing of multiple renderings

7. clinical description of the specified view

8. volume and display relative annotations, including graphics, text and overlays

9. membership in a collection of related Volumetric Presentation States intended to be processed or displayed together

10. the temporal position within a set of temporally related Volumetric Presentation States

11. recommendations for animating the view

12. reference to an image depicting the view described by the Presentation State

The Planar MPR Volumetric Presentation State IOD is used in two SOP Classes as defined in PS3.4 Storage Service Class, a SOP Class for grayscale Presentation States intended for presenting a single input, and a SOP Class for Presentation States that composite multiple inputs into a single presentation. These are distinguished by their SOP Class UID and by the Enumerated Value of the mandatory Attribute in the MPR Volumetric Presentation State Display Module, Pixel Presentation (0008,9205).

#### A.80.1.2 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.80.1.3 Planar MPR Volumetric Presentation State IOD Module Table

Table A.80.1-1 specifies the Modules of the Planar MPR Volumetric Presentation State IOD.

#### A.80.1.4 Planar MPR Volumetric Presentation State IOD Content Constraints

##### A.80.1.4.1 Presentation Input Restrictions

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

If the value of Pixel Presentation (0008,9205) is MONOCHROME, the Volumetric Presentation State Input Sequence (0070,1201) shall have only a single Item.

##### A.80.1.4.2 Multi-Planar Reconstruction Style

Multi-Planar Reconstruction Style (0070,1501) shall have a value of PLANAR.

##### A.80.1.4.3 Graphic Annotation Module

The following Attributes, if present, shall have a value of DISPLAY:

- Bounding Box Annotation Units (0070,0003)

- Anchor Point Annotation Units (0070,0004)

- Graphic Annotation Units (0070,0005)

- Compound Graphic Units (0070,0282)

The Display coordinates are relative to the Volumetric Presentation View produced by this Presentation State.

### Note

See Annex XXX “Volumetric Presentation States (Informative)” in PS3.17 for guidance on usage of the graphic annotation styles available in this IOD.

##### A.80.1.4.4 Volume Cropping Module

The values of Volume Cropping Method (0070,1302) shall be selected from the following:

Enumerated Values:

BOUNDING_BOX

OBLIQUE_PLANES

INCLUDE_SEG

EXCLUDE_SEG

##### A.80.1.4.5 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 Section C.11.23.3.
