Several different styles of animation are defined in Volumetric Presentation States. In general, an animation style will vary either the input, processing, or view geometry in order to produce a varying presentation view. This section describes each of the animation styles and how it produces an animated view.
A Presentation Animation Style (0070,1A01) value of INPUT_SEQ indicates that Input Sequence Animation is being specified. In this animation style, a single Volumetric Presentation State is defined which includes input items in the Volumetric Presentation State Input Sequence (0070,1201) with different values of Input Sequence Position Index (0070,1203). The animated presentation view is produced by sequencing through values of Input Sequence Position Index (0070,1203) at a specified animation rate Recommended Animation Rate (0070,1A03), where each value of the index produces one 'frame' of the animated view from inputs that have that value of Input Sequence Position Index (0070,1203). See Figure FF.3.2-1.
Note
For example, a set of inputs could be temporally related volumes of a moving anatomical structure like the heart.
There may be more than one input item in Volumetric Presentation State Input Sequence (0070,1201) with the same value of Input Sequence Position Index (0070,1203), in which case the inputs are processed together to produce the frame of the animated view.
Note
For example, pairs of input items could represent the same volume input at a point in time with two different segmentation croppings (representing different organ structures) that are blended together into a single view.
