A Proposed Warped Choi Williams Time Frequency Distribution Applied to Doppler Blood Flow Measurement
One of the main goals in ultrasonic Doppler blood flow measurement is the estimation of the mean velocity. The Doppler signal’s instantaneous frequency has traditionally been used to estimate the mean velocity. In this work, a non-uniform discrete time frequency distribution is proposed: the warped discrete Choi Williams distribution (WTFDCW). The proposed procedure estimates the instantaneous ...
متن کاملTechnical note: measuring portal blood flow in sheep using an ultrasonic transit time flow probe.
Our objective was to validate the use of an ultrasonic transit-time flowmeter for the measurement of portal blood flow (PBF) in sheep. Data recorded with this technique were compared with those obtained with an indicator dilution method, and probes were calibrated in vivo. Wethers were fitted with catheters in the portal, jejunal, and ruminal veins and in a mesenteric artery. Ultrasonic flow pr...
متن کاملBarefoot Running
Running barefoot is associated with a substantially lower prevalence of acute injuries of the ankle and chronic injuries of the lower leg in developing countries, but well-designed studies of the effects of barefoot and shod running on injury are lacking. Laboratory studies show that the energy cost of running is reduced by about 4% when the feet are not shod. In spite of these apparent benefit...
متن کاملInfluence of probe pressure on the diffuse correlation spectroscopy blood flow signal: extra-cerebral contributions
A pilot study explores relative contributions of extra-cerebral (scalp/skull) versus brain (cerebral) tissues to the blood flow index determined by diffuse correlation spectroscopy (DCS). Microvascular DCS flow measurements were made on the head during baseline and breath-holding/hyperventilation tasks, both with and without pressure. Baseline (resting) data enabled estimation of extra-cerebral...
متن کاملQuantitative cerebral blood flow measurements in the rat using a beta-probe and H2 15O.
Beta-probes are a relatively new tool for tracer kinetic studies in animals. They are highly suited to evaluate new positron emission tomography tracers or measure physiologic parameters at rest and after some kind of stimulation or intervention. In many of these experiments, the knowledge of CBF is highly important. Thus, the purpose of this study was to evaluate the method of CBF measurements...
