Fully-Automatic Method for Assessment of Flow-Mediated Dilation

摘要

The most popular method for assessment the endothelial function, called flow-mediated dilation, is based on monitoring how the brachial artery diameter changes in hyperemia state. All of the existing methods that assess FMD are exceedingly time consuming, as they require supervising analysis of the whole video. The presented method fully-automatically analyzes the videos and returns the FMD value using region of interest (ROI) defined by the operator. The main contributions of this paper are: minimizing inter and intra-observer variability; eliminating supervision from the analysis; applying more informative techniques than edge detectors; providing dataset which can be used by other researchers to test their fully-automatic methods.
