Fractal Rigidity in Migraine [PDF]
, 2003 We study the middle cerebral artery blood flow velocity (MCAfv) in humans using transcranial Doppler ultrasonography (TCD). Scaling properties of time series of the axial flow velocity averaged over a cardiac beat interval may be characterized by two ...

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.

Revealing Intraosseous Blood Flow in the Human Tibia With Ultrasound
JBMR Plus, 2021 Intraosseous blood circulation is thought to have a critical role in bone growth and remodeling, fracture healing, and bone disorders. However, it is rarely considered in clinical practice because of the absence of a suitable noninvasive in vivo ...
