The automated assesment of artery hemodynamic parameters from ultrasound video

2012

The custom designed video processing software for analysis of B-mode and Doppler-mode ultrasound video has been proposed in this work. The software allows adjusting user-defined thresholds and tolerance levels to enhance contour detection in noisy and artifacted ultrasound images. The developed software is able to evaluate 16 hemodynamic parameters (artery diameter, pulse rate and flow velocity related parameters) in each cardiac cycle. The measurements were performed intermittently recording artery diameter (B-mode) and flow velocity (Doppler-mode). Software has validated in femoral artery measurements. The hemodynamic parameters computed by software were consistent with those obtained by …

Comparison of remote photoplethysmography signals acquired by ultra-low noise camera and conventional camera during physiological tests

2017

In present study, remote photoplethysmography signals acquired by ultra-low noise camera and conventional camera were compared during different skin microcirculation provocation tests. The aim of work was to reveal how much of camera dynamic range and noise contribute to blood perfusion signal quality. Results demonstrate comparable capabilities of both cameras for skin perfusion monitoring.
