From: Segmented golden ratio radial reordering for dynamic cardiac MRI with variable temporal resolution
a) Conventional GA method, when applied to ECG-gated cardiac imaging applications, results in non-uniform sampling of k-space; b) The proposed segmented GA method addresses this issue by performing golden-ratio acquisition inside each segment within a R-R interval and thus provides a near-uniform k-space sampling of arbitrary acquisition window length and position within a cardiac cycle.
