A mobile ultrasonic stratified flow velocity measurement device, which utilizes a pair of ultrasonic transducers, was characterized by its low power consumption and the ability to measure multi-layer ...

Abstract: One of the major tasks in multiple-phase flow detection is flow velocity estimation. According to the cross-correlation (CC) measurement principle, the electrical resistance tomography (ERT) ...

Little is known about the influence of upright positioning on real-time cerebral flow variables in patients with stroke. We aimed to assess whether cerebral blood flow velocity (CBFV) changes ...

Objective: To evaluate the relationship between large artery stiffness and coronary flow velocity reserve (CFVR). Patients and methods: 102 consecutive subjects (mean (SD) age 62 (10) years) without ...

Twenty-three patients were investigated during diagnostic right and left cardiac catheterization with an electromagnetic catheter-tip velocity probe. The catheter contained a pressure lumen for ...

Under the agreement, High-Velocity Startups (HVS) will help Fusion Flow expand its AI Booster platform to identify productivity enhancements and cost reductions for enterprises. Fusion Flow will ...

Similar to testing a car, a team of researchers at UBC Okanagan has been test-driving a number of mechanical heart valves ...

This study aimed to evaluate the concordance of 4D flow CMR and TTE to estimate V Peak and grade AS severity. Second, this study evaluated the utility of 4D flow CMR peak velocity in discordant TTE ...

The study analyzes the effects of viscosity, eccentricity, flow and shaft rotation on the tangential and axial velocity profiles and on the hydrodynamic losses. It evaluates the performance of the ...

Abstract: We demonstrate a new method to recover 4D blood flow over the entire ventricle from partial blood velocity measurements using multiple 3D+t colour Doppler images and ventricular wall motion ...

AIM To study continuously cerebral blood flow velocity in the middle cerebral artery before, during, and after tube feeding in neonates. METHOD Cerebral blood flow velocity was measured in 14 neonates ...
