Ultrasonic flow meters are non-invasive devices that use acoustic vibrations to determine the flow rate of a liquid. There are two types of ultrasonic flow meters – Doppler and transit time. Both ...

In daily clinical practice, the possibilities of evaluating the quality of the microcirculation of certain territories of ‘vascular’ patients are relatively limited compared with the many tools for ...

The Doppler effect, discovered in 1842 by Christian Doppler, is familiar to most of us; stationary observers of waves such as sound waves will see wavelengths that depend on the relative motion ...

The Indus Doppler Flow Velocity System is a high-frequency, real-time pulsed Doppler measurement tool with built-in data processing software intended to assess small animals' cardiovascular health.

Is there any clinical correlation between Doppler flow data and the degree of stenosis in arteriovenous (AV) grafts for dialysis access? If so, are Doppler flow data a reliable indicator of decline in ...

This special structure creates a unique ultrasonographic appearance as described by Zalel and colleagues. [3] The typical sonographic appearance of the LNG device includes (Figures 1 and 2): Detection ...

Coronary flow reserve (CFR) is a key sign of coronary artery disease, namely how the coronary arteries that feed blood to the heart may adapt to various physiological situations such as exercise, ...

Engineers at the Japanese electronics and materials company Kyocera have developed a tiny optical sensor for measuring blood-flow – and are investigating wearable technology applications ahead of a ...

Recent advances in flow sensing have resulted in more accurate, durable, and economical meters. Increasingly important is the ability to interface meters with a computer for instantaneous flow readout ...

Medical ultrasound is a non-invasive method for imaging the body’s internal structures like organs. It processes by transmitting high-frequency sound waves into the body and measuring the reflections ...
