Doppler ultrasound - basics revisited
British Journal of Nursing, 2006Palpation of pedal pulses alone is known to be an unreliable indicator for the presence of arterial disease. Using portable Doppler ultrasound to measure the resting ankle brachial pressure index is superior to palpation of peripheral pulses as an assessment of the adequacy of the arterial supply in the lower limb. Revisiting basics, this article aims

Doppler ultrasound monitoring technology
BJOG: An International Journal of Obstetrics & Gynaecology, 1993ABSTRACTDevelopments in the signal processing of Doppler ultrasound used for the detection of fetal heart rate (FHR) have improved the operation of cardiotocographs. These developments are reviewed and the advantages and disadvantages of the various Doppler and signal processing methods are compared.

Due to its unique temporal resolution in the range of milliseconds, Doppler ultrasound has become one of the clinically and scientifically most fruitful and innovative noninvasive techniques for the investigation of the cerebral circulation. This refers to extracranial continuous-wave Doppler sonography (ECD) of the extracranial brain arteries ...

Ultrasound has many uses in areas of medicine associated with anaesthesia. It is used for imaging, visualisation of needle and catheter positioning, therapy and, together with the Doppler effect, for measurement of flow velocity. Real-time information can be obtained with ease, and with the low energies used, diagnostic equipment exposures are not ...

[Transcranial Doppler ultrasound].
Canadian Association of Radiologists journal = Journal l'Association canadienne des radiologistes, 1992Over the last decade, transcranial Doppler examination of the cerebral vessels has been made possible by the development of a high-intensity, low-frequency (2 MHz) pulse probe. The middle, the anterior and the posterior cerebral arteries, the cavernous portion of the carotid artery and the basilar artery can thus be easily studied transtemporally or ...

The first studies on ultrasound for measurement of flow velocity in blood vessels were published 1954 by Kalmus 88 and 1957 by Baldes et al.14. In 1957, Satomura 164 described an ultrasound method used to inspect the function of the heart and in 1959 and 1960, he reported on its application in peripheral arteries 165, 166 Franklin et al.61 in 1961 ...
