FFF.2.2.1.4 Example

An example of a 4 position peripheral stepping acquisition with different frame-rates is provided. One group is only 2 Frames (e.g., due to fast contrast bolus) and will be skipped for display purposes.

The whole image is reviewed in looping mode:

Below are the encoded values of the key attributes of this example:

Preferred Playback Sequencing (0018,1244) = 0
Frame Display Sequence (0008,9458)
Item 1
>Start Trim (0008,2142) = 1
>Stop Trim (0008,2143) = 17
>Skip Frame Range Flag (0008,9460) = DISPLAY
>Recommended Display Frame Rate in Float (0008,9459) = 4.0
Item 2
>Start Trim (0008,2142) = 18
>Stop Trim (0008,2143) = 25
>Skip Frame Range Flag (0008,9460) = DISPLAY
>Recommended Display Frame Rate in Float (0008,9459) = 2.0
Item 3
>Start Trim (0008,2142) = 26
>Stop Trim (0008,2143) = 27
>Skip Frame Range Flag (0008,9460) = SKIP
>Recommended Display Frame Rate in Float (0008,9459) = 2.0
Item 4
>Start Trim (0008,2142) = 28
>Stop Trim (0008,2143) = 36
>Skip Frame Range Flag (0008,9460) = DISPLAY
>Recommended Display Frame Rate in Float (0008,9459) = 1.5
