Non-accelerated (a) and accelerated (b) results are compared, where most of the acceleration was used to increase temporal resolution. While a mid-systolic phase is show in (a) and (b), an early-systolic phase is shown instead in (c). The temporal frequency content for the ROI in (c) is plotted in (d), confirming that as expected, the accelerated results (3.5-fold) feature signal over a frequency range about twice as wide as the non-accelerated results (1.0-fold).
