A new framework for assessing subject-specific whole brain circulation and perfusion using MRI-based measurements and a multi-scale continuous flow model

Vascular network of the frog tongue.
Node centers are indicated with black dots. The medial axis of the network structure is shown as the set of lines connecting the nodes (red lines: arterial network, blue lines: venous network). The grey area within the tongue tissue indicates the support function ηϵ(x − xk) (15) summed up for all terminals. The red rectangle in the lower field is the small FOV used for demonstrating scale invariance.
