Cerebral vascular disease is responsible for nearly 800 000 hospital admissions annually with a total healthcare cost of $34 billion. Neuro-interventional surgery is at the forefront of fast-response assessment and intervention to assess patients’ health using digital subtraction angiography (DSA). Unfortunately, cerebral blood flow cannot be reliably measured with DSA during intervention. In t...

Effects of 12 Weeks Aerobic Exercise (High-Intensity Interval Training or Moderate Intensity Continuous Training) with and without Blood Flow Restriction on Anthropometric Indices in Women Cardiotoxicity after Breast Cancer Treatment

Turbulent flow over wall-mounted cube in a channel was investigated numerically using Large Eddy Simulation. The Selective Structure Function model was used to determine eddy viscosity that appeared in the subgrid scale stress terms in momentum equations. Studies were carried out for the flows with Reynolds number ranging from 1000 to 40000. To evaluate the computational results, data was compa...

The current empirical study was conducted to investigate the wall neighborhood impact on the two-dimensional flow structure and heat transfer enhancement behind a square cylinder. The low- velocity open-circle wind tunnel was used to carry out the study tests considering the cylinder diameter (D)-based Reynolds number (ReD) of 5130. The selected items to compare were different gap he...

In this work, a simple and low-cost air flow sensor, based on a novel fiber-optic sensing technique has been developed for monitoring air flows rates supplied by a neonatal ventilator to support infants in intensive care units. The device is based on a fiber optic sensing technique allowing (a) the immunity to light intensity variations independent by measurand and (b) the reduction of typical ...

to compute the optic flow along intensity change curves. The flow is computed locally at corners, determined as edge points of high curvature, by cross correlation over time. The (full) flow is then computed along edge contours by means of a combined wave/diffusion process. MCMAP has been implemented on a Transputer array using a mixed paradigm of a pipeline and a processor farm. A fast algorit...

We present an optically encoded photoacoustic (PA) flow imaging method based on optical-resolution PA microscopy. An intensity-modulated continuous-wave laser photothermally encodes the flowing medium, and a pulsed laser generates PA waves to image the encoded heat pattern. Flow speeds can be calculated by cross correlation. The method was validated in phantoms at flow speeds ranging from 0.23 ...

OBJECTIVES The study compared flow reserve indices by magnetic resonance imaging (MRI) with quantitative measures of coronary angiography and positron emission tomography (PET). BACKGROUND The noninvasive evaluation of myocardial flow by MRI has recently been introduced. However, a comparison to quantitative flow measurement as assessed by PET has not been reported in patients with coronary a...

BACKGROUND AND PURPOSE Intra-arterial (IA) rescue procedures are increasingly used to treat acute ischemic stroke. We implemented continuous transcranial Doppler (TCD) monitoring during these procedures to detect any potentially harmful flow changes. Here, we report diagnostic criteria and yield of TCD monitoring. METHODS We studied consecutive acute stroke patients who underwent IA reperfusi...
