Doppler Ultrasound Blood Flow Measurement System for Assessing Coronary Revascularization
This work describes a Doppler ultrasound system for measuring blood flow. The system is intended to be used for assessing coronary implants and bypass operations. Quantifying the blood flow through these implants/bypasses is an important task to ensure the chirurgical process, thus, reducing both the post-chirurgical and death risks. The system is based on an open architecture that is portable ...
متن کاملTissue blood flow measurement by laser Doppler technique
Measurement of blood flow and the effects of different factors on tissue blood flow are important fields of research in physiology and pharmacology. So far, different methods have been innovated, using laser light is the Last one. In this article history, principles and specifications of laser technique along with its advantages and disadvantages ( in comparison with other methods) are revie...

15 صفحه اولContinuous wave Doppler ultrasound in evaluation of cerebral blood flow in neonates.
The cerebral circulation of 25 normal term infants was investigated using continuous wave Doppler ultrasound. Serial blood flow velocity signals were obtained from the common carotid and anterior cerebral arteries during the first week of life. The records were processed using a frequency spectrum analyser to provide cerebral blood velocity waveforms. The pulsatility index (PI), A/B ratio, and ...
متن کاملNewer techniques of cerebral blood flow measurement.
• A variety of methods for measuring cerebral blood flow have been developed in the past 25 years since Kety and Schmidt developed their method based on the Fick principle. None of the currently used methods approaches the clinical ideal, since none of the techniques are accurate, reproducible and noninvasive. Most accurate techniques involve catheterization of internal carotid artery and/or ju...
