Visualisation of the individual root network results for a nominal participant. The network for each root is visualised from an inferior position along the inferior-superior axis (top row). Root network quality scores, \(Q\), (middle row) and pulsatility, \({p}_{pi}\) (bottom row) at different distances, \(d\left(\mathbf{x},{\mathbf{x}}^{r}\right)\) for left and right ICAs and BA are then plotted. Overlaid measurement values for \({p}_{pi}\), \({p}_{df}\) , and \({p}_{tc}\) are presented in the bottom row for comparison. As \({p}_{tc}\) integrates all high-quality \({p}_{pi}\) samples, it provides a more comprehensive description of the pulsatility for each subvascular tree. Abbreviations: basilar artery (BA), distance (d), internal carotid artery (ICA), quality (Q).
