Effect of blood's velocity on blood resistivity [PDF]
, 1998 Blood resistivity is an important quantity whose value influences the results of various methods used in the study of heart and circulation. In this paper, the relationship between blood resistivity and velocity of blood flow was evaluated and analyzed ...

Calibration-free in vivo transverse blood flowmetry based on cross correlation of slow time profiles from photoacoustic microscopy [PDF]
, 2013 We propose a cross-correlation-based method to measure blood-flow velocity by using photoacoustic microscopy. Unlike in previous autocorrelation-based methods, the measured flow velocity here is independent of particle size.

Cerebral blood flow velocity is associated with endothelial function in men [PDF]
Journal of Men's Health, 2021 Background and objective: Reduction in cerebral blood flow with aging leads to cognitive decline and brain atrophy. Cerebrovascular hemodynamics are associated with vascular function.

Velocimetry of red blood cells in microvessels by the dual-slit method: Effect of velocity gradients [PDF]
, 2012 The dual-slit is a photometric technique used for the measurement of red blood cell (RBC) velocity in microvessels. Two photometric windows (slits) are positioned along the vessel.

Pulsatile blood flow through a constricted porous artery [PDF]
, 2020 In this paper a speculative study of an incompressible Newtonian blood flow through a constricted porous channel and pulsatile nature is inspected. Porosity parameter λ is incorporated in the momentum equation.
