The study presents a novel, real-time transputer-based system for non-invasive measurement of arterial pulse wave velocity using Doppler ultrasound.
Answers are grounded in this paper and cite their sources.
May simplify real-time Doppler PWV assessment without extra hardware; leaves open clinical validation before any practice change.
A system for the measurement of arterial pulse wave velocity is described. A personal computer (PC) plug-in transputer board is used to process the audio signals from two pocket Doppler ultrasound units. The transputer is used to provide a set of bandpass digital filters on two channels. The times of excursion of power through thresholds in each filter are recorded and used to estimate the onset of systolic flow. The system does not require an additional spectrum analyser and can work in real time. The transputer architecture provides for easy integration into any wider physiological measurement system.
