Effects of epinephrine on coronary microvascular diameters.
This study was designed to examine the hypothesis that epinephrine has nonuniform effects on coronary microvascular diameters. Measurements of coronary microvascular diameter were completed in anesthetized, open-chest cat preparations in which the epicardial microcirculation was viewed through an intravital microscope using stroboscopic epi-illumination. Images of coronary microvessels were dig...
متن کاملRevised formulas for summarizing retinal vessel diameters.
Background/Purpose. Recent findings suggest that an objective assessment of retinal vessel caliber from fundus photographs provide information about the association of microvascular characteristics with macrovascular disease. Current methods used to quantify retinal vessel caliber, introduced by Parr(1,2) and Hubbard,(3) are not independent of scale and are affected by the number of vessels. To...
متن کاملNovel Computerized Method for Measurement of Retinal Vessel Diameters
Several clinical studies reveal the relationship between alterations in the topologies of the human retinal blood vessel, the outcrop and the disease evolution, such as diabetic retinopathy, hypertensive retinopathy, and macular degeneration. Indeed, the detection of these vascular changes always has gaps. In addition, the manual steps are slow, which may be subjected to a bias of the perceiver...
متن کاملComputer algorithms for the automated measurement of retinal arteriolar diameters.
AIMS Quantification of retinal vascular change is difficult and manual measurements of vascular features are slow and subject to observer bias. These problems may be overcome using computer algorithms. Three automated methods and a manual method for measurement of arteriolar diameters from digitised red-free retinal photographs were compared. METHODS 60 diameters (in pixels) measured by manua...
متن کاملMeasurement of Vessel Diameters on Retinal Images for Cardiovascular Studies
Accurate measurement of vessel diameters on retinal images plays an important part in diagnosing cardiovascular diseases. In this study, a method of vessel diameter measurement has been developed incorporating with a tracking technique. Twin Gaussian functions are introduced to model the distribution of grey level profile over a vessel cross section. The tracking technique is utilised to study ...
