Retinal Vessel Analyzer (RVA)--design and function.
The Retinal Vessel Analyzer (RVA) is a measuring device for online measurement of the diameter of retinal vessels in relation to time and locations along the vessel. It is furthermore provided with several tools for analyzing the measured data. The fundamental components consist of a fundus camera with CCD measuring camera attached and an advanced image-processing unit. The measurement range is...
متن کاملRetinal Vessel Analysis (RVA) in the Context of Subarachnoid Hemorrhage - A Proof of Concept Study
BACKGROUND Timely detection of impending delayed cerebral ischemia after subarachnoid hemorrhage (SAH) is essential to improve outcome, but poses a diagnostic challenge. Retinal vessels as an embryological part of the intracranial vasculature are easily accessible for analysis and may hold the key to a new and non-invasive monitoring technique. This investigation aims to determine the feasibili...
متن کاملAltair: Automatic Image Analyzer to Assess Retinal Vessel Caliber
The scope of this work is to develop a technological platform specialized in assessing retinal vessel caliber and describing the relationship of the results obtained to cardiovascular risk. Population studies conducted have found retinal vessel caliber to be related to the risk of hypertension, left ventricular hypertrophy, metabolic syndrome, stroke, and coronary artery disease. The vascular s...
متن کاملRetinal Images Analyzer †
A software application is presented, for the detection and measurement of retinal vessels in fundoscopy images. This software is comprised by a measurement module and a Graphical User Interface (GUI) module. The measurement module employs image processing methods and operates in batch mode, to segment retinal vessels in the input image. In addition, the measurement module estimates the diameter...
متن کاملRetinal vessel segmentation using a multi-scale medialness function
Recently, automated segmentation of retinal vessels in optic fundus images has been an important focus of much research. In this paper, we propose a multi-scale method to segment retinal vessels based on a weighted two-dimensional (2D) medialness function. The results of the medialness function are first multiplied by the eigenvalues of the Hessian matrix. Next, centerlines of vessels are extra...
