"The paper deals with modelling the cerebral perfusion (CP) using an advanced microstructure based model. The presented approach is based on a layered representation of the vascular tree hierarchies; in each-one the strongly heterogeneous medium described by the Biot model is upscaled using the two-scale homogenization of a periodic structure. The model involves macroscopic pressures associated with different compartments of the perfusion system. Convected diffusion of the contrast medium is considered; the spatial macroscopic distribution of its concentration is the measure of the perfusion." .
