Blood Flow Velocity in a Patient with Takayasu's Arteritis

Japanese Heart Journal, 1972
Blood flow velocity was recorded by using Doppler transcutaneous flowmeter and Doppler catheter flowmeter in an 18-year-old woman with Takayasu's arteritis. Although no right radial artery pulse was felt by palpation, significant decrease and slow rise of the peak blood flow velocity, and inconspicuous dicrotic notch was observed and recorded from the ...

In vivo label-free measurement of blood flow velocity symmetry based on dual line scanning third-harmonic generation microscopy excited at the 1700 nm window

Journal of Innovative Optical Health Sciences
Measurement of blood flow velocity is key to understanding physiology and pathology in vivo. While most measurements are performed at the middle of the blood vessel, little research has been done on characterizing the instantaneous blood flow velocity ...

Fabrication of a Stable, Low‐Cost, Patient‐Specific, Brain Phantom with Ventricles for Ultrasound Imaging

Advanced Engineering Materials, EarlyView.
Patient‐specific brain phantoms can replace animal trials, aid presurgical training, and enable in silico disease research on cerebrospinal fluid and ventricles. This study presents a method to create ventricular brain phantoms from three‐dimensional magnetic resonance images brain scans, resulting in durable, tunable, reproducible models that mimic ...

The Importance of Velocity Acceleration to Flow-Mediated Dilation

International Journal of Vascular Medicine, 2012
The validity of the flow-mediated dilation test has been questioned due to the lack of normalization to the primary stimulus, shear stress. Shear stress can be calculated using Poiseuille's law.
