ABSTRACT
The article presents the comparison of Doppler Ultrasonic Waveforms processed by zero crossing and spectrographic techniques in the diagnosis of peripheral arterial disease. The development of the transcutaneous Doppler ultrasonic blood flowmeter has intensified the search for noninvasive methods of assessment of peripheral arterial disease. The standard, commercially available Doppler blood flowmeter uses continuous wave ultrasound and has an output proportional to blood velocity which uses the zero crossing technique to measure the Doppler frequency. Sonograms of the Doppler sound for one pulse wave were obtained for each arterial site. A straightforward use of systolic pressure ratios gave good agreement with the arteriographic diagnosis.
