##### FF.2.4.2.2 Presentation Sequence Animation

A Presentation Animation Style (0070,1A01) value of PRESENTATION_SEQ indicates that Presentation Sequence Animation is being specified. In this animation style, a set of Volumetric Presentation States are applied sequentially. See Figure FF.3.2-2.

### Note

One example of the use of presentation sequence animation is a view of a moving heart wherein a stent is at a stationary position at the center of the view. Because the geometry of each view frame is slightly different, separate Volumetric Presentation State instances are required for each view frame.

Each Volumetric Presentation State of the set is identified by having the same value of Presentation Sequence Collection UID (0070,1102). The order of application of these Presentation States is determined by the value of Presentation Sequence Position Index (0070,1103) defined in the Presentation State. The animated presentation view is produced by sequencing through values of presentation sequence position index at a specified animation rate Recommended Animation Rate (0070,1A03), where each value of the index produces one 'frame' of the animated view produced by that Volumetric Presentation State.
