Background After the occlusion of an internal carotid artery the principal source of collateral
flow is through the arteries of the circle of Willis, but the size and patency of these arteries …

Quantification of nonlinear interactions between two nonstationary signals presents a
computational challenge in different research fields, especially for assessments of …

Quantitative, multislice dynamic susceptibility contrast-enhanced MRI perfusion
