2.11 Dual PRF Unfolding
In order to increase the mean velocity dynamic range, the dual PRF unfolding algorithm (= staggered
PRF ) has been implemented.
Three modes are available:
● Two times unfolding (2/3 stagger staggering; increases velocity dynamic range by factor 2)
● Three times unfolding (3/4 staggering; increases velocity dynamic range by factor 3)
● Four times unfolding (4/5 staggering; increases velocity dynamic range by factor 4)
