TL;DR: The instantaneous wave-free ratio calculated over this period produces a drug-free index of stenosis severity comparable to FFR, and intracoronary resistance is naturally constant and minimized during the wave- free period.

TL;DR: This analysis shows that forward running wavelets dominate during both the acceleration and deceleration phases of blood flow in the aorta, and is a time domain analysis which can be applied to nonperiodic or transient flow.

TL;DR: In this article, a one-dimensional model of a vascular network based on space-time variables is investigated, and the assumptions involved in constructing the system in terms of area-mass flux (A,Q), area-velocity, pressurevelocity (p,u), and pressuremass flux(p,Q) variables are discussed.

TL;DR: A new approach is proposed that uses measurements of vessel diameters and branching angles as a validation criterion to compare the authors' segmented images with those hand segmented from public databases, and demonstrated that borders found by the method are less biased and follow more consistently the border of the vessel and therefore they yield more confident geometric values.

TL;DR: The inclusion of wall visco-elasticity in the numerical model reduced the underdamped high-frequency oscillations obtained using a purely elastic tube law, especially in peripheral vessels, which was reported in this paper.
