Transcutaneous Doppler ultrasound measurement of superior mesenteric artery blood flow in man.
A duplex scanner which consists of a real time two dimensional scanner and a pulsed Doppler flowmeter was used to measure superior mesenteric blood flow in 70 healthy subjects. By processing the Doppler shift signals, the instantaneous average Doppler shift frequency and then the instantaneous average velocity of the flow rate were calculated. Both diameter of the vessel and angle between vesse...
متن کاملDoppler 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 ...

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...
متن کاملClinical diagnosis by transcutaneous Doppler ultrasound.
Introduction The past few years have seen a vast proliferation in the use of ultrasound to diagnose circulatory disorders. This increasing interest reflects the fact that many tests are non-invasive, reliable, provide bedside answers and do not require large investment of equipment or personnel. Ultrasound systems have been used clinically in two ways. Firstly, ultrasound can provide an anatomi...
متن کاملMeasurement of pulp blood flow rates in maxillary anterior teeth using ultrasound Doppler flowmetry.
AIM To measure pulp blood flow rates of clinically normal maxillary anterior teeth of healthy adults using ultrasound Doppler flowmetry (UDF). METHODOLOGY A total of 359 anterior teeth from 63 patients (mean age, 29.8 years; range, 22-52 years; 26 females and 36 males) were included. The data were collected according to tooth type (three groups: central incisors, lateral incisors and canines)...
