On-chip laser Doppler vibrometer for arterial pulse wave velocity measurement
Pulse wave velocity (PWV) is an important marker for cardiovascular risk. The Laser Doppler vibrometry has been suggested as a potential technique to measure the local carotid PWV by measuring the transit time of the pulse wave between two locations along the common carotid artery (CCA) from skin surface vibrations. However, the present LDV setups are still bulky and difficult to handle. We pre...
متن کاملPulse wave velocity measurement
The article deals with the investigation of pulse wave propagation in arteries. A part of work involves also design and realization of devices serving for scanning of pulse wave by reflective photoplethysmography. The work describes a use of microcontroller serving for data flow control, communication and analog signal digitalization using integrated analog to digital converter.
متن کاملAccuracy of arterial pulse-wave velocity measurement using MR.
The performance of a one-dimensional MR technique for the estimation of pulse-wave velocity in the aorta was evaluated. An expression for the error in this estimate was formulated and verified both by simulation and by experiment. On the basis of this formulation, guidelines for increasing the efficiency of the acquisition were established. The technique was further validated by comparison with...

متن کاملNovel Methods for Pulse Wave Velocity Measurement
The great incidence of cardiovascular (CV) diseases in the world spurs the search for new solutions to enable an early detection of pathological processes and provides more precise diagnosis based in multi-parameters assessment. The pulse wave velocity (PWV) is considered one of the most important clinical parameters for evaluate the CV risk, vascular adaptation, and therapeutic efficacy. Sever...
