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 ...

Laser Doppler flowmetry (LDF) is a technique for real-time assessment of microcirculation blood flow. LDF can be used for non-invasive perfusion monitoring (for example skin perfusion monitoring), or ...

Methods and Results— In an open-chest pig model, CFR thermo was measured in the left anterior descending (LAD) artery and compared with CFR Doppler and CFR flow, measured with an external flow probe ...

Compared with the low-frequency Doppler current meter, the HF wideband current meter has a lower measurement blind area and higher measurement resolution, although it has a more confined measurement ...

The purpose of this study was to assess the ability of transcranial Doppler ultrasonography to detect selective circulatory changes during cognitive activity.We measured cerebral artery flow velocity ...

For patients with upper GI bleeding, primarily from ulcers, rebleeding at 30 days was significantly lower when a Doppler probe was added to standard hemostasis, new research has shown.

We lack non-invasive tools for evaluating the coronary and renal microcirculations. Since cutaneous Doppler laser exploration has evidenced impaired cutaneous microvascular responses in coronary ...

2.6 Automated ABPI devices include doppler-based, oscillometry-based and plethysmography-based devices. Doppler-based devices use a doppler probe and provide doppler waveform signals as an output.

Clinical Study Published: 07 April 2004 Reproducibility of blood flow velocity measurements using colour decoded Doppler imaging E T Matthiessen, O Zeitz, G Richard & M Klemm Eye 18, 400–405 ...

Regulatory information MiraQ cardiac transit time flow measurement and high-frequency ultrasound system is a CE-marked class IIa medical device, and the probes used with the MiraQ system are CE-marked ...
