#### C.11.22.2 Presentation Sequence Collection UID

A set of Presentation States with the same value of Presentation Sequence Collection UID (0070,1102) defines a sequence of views. The Presentation Sequence Position Index (0070,1103) specifies the order of Presentation States within this Presentation Sequence.

Presentation States in such a collection may be used in an animation. In this form of animation, Presentation States in the set are applied in sequential order to produce a moving view. Typically, the same input(s) are used in each Presentation State of the set. See the PRESENTATION_SEQ animation style in Section C.11.29.

### Note

Examples include:

- animation of a sequence of MPRs depicting the left ventricle of the heart at each point in a cardiac cycle with slightly different geometries

- animation of a sequence of views throughout the cardiac cycle in which a stent appears stationary in the middle of the view

- a sequence of parallel slices of an anatomical structure (that aren't necessarily going to be animated)

Presentation States in such a collection that are not used in an animation leave the style of presentation to the discretion of the display application, such as by display of all related presentations in a "light-box" format or in a single display frame with manual scrolling of the views.

All Presentation States with the same value of Presentation Sequence Collection UID (0070,1102) shall share the same Volumetric Presentation State Reference Coordinate System.
