Pulse 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 کاملA one-dimensional model for variations of longitudinal wave velocity under different thermal conditions
Ultrasonic testing is a versatile and important nondestructive testing method. In many industrial applications, ultrasonic testing is carried out at relatively high temperatures. Since the ultrasonic w...
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...
متن کاملAn Optical Measurement System to Measure Velocity and Provide Shock Wave Pressure Diagrams
This paper introduces an optical measurement system for shock wave characteristics. The system works by mountinga metal plate attached to spring mounts against the shock wavefront. This set is sealed and can plot the shock wave pressure diagram by measuring plate's displacement, radiation and changing the reflection of light during shock wave conflict, and converting these optical data to volta...
متن کاملRapid measurement of aortic wave velocity: in vivo evaluation.
A 1D MR sequence has been developed for determining aortic flow wave velocity (WV), a metric of arterial compliance, within a single cardiac cycle. Studies were carried out on the thoracic aortas of 10 normal volunteers. Correlative WV data were also acquired from each subject using a conventional phase-velocity 2D mapping technique. Aortic WV in this cohort was found to range from 411 to 714 c...
