Distributed parameter arterial tree modeling using D mode ultrasound images

Abstract

Distributed parameter arterial tree model, based on transmission line theory is proposed. Adequacy of the model is confirmed using noninvasive "in vivo" ultrasound Doppler images. Ultrasound measurements in three characteristic locations of human arterial tree are performed. Comprised model enables to acquire typical blood flow time functions in 40 arteries. Parameters of the model are related to relevant geometrical and mechanical arteries properties. The model can be used in the research into the influence of blood vessel mechanical parameters on the form of flow time function as well as when estimating possibilities of diagnostics of blood flow system lesion.

Electrical Artery Model for the Evaluation of Non-Linear Compliance

“…when blood flow is considered to be analogous to the flow of electric current and voltagecurrent relation is used to describe pressure-flow relation in human arteries, is one of the principal methods employed in many human circulation models. It is widely used for both -lumped [1] and distributed [2] representation.…”
