Fundus photography and fluorescein angiography Fluorescein angiography
Fluorescein angiography is a clinical diagnostic test procedure in which rapid-sequence photography is performed after intravenous injection of sodium fluorescein. The procedure allows the documentation of the retinal circulation. Of equal importance is the ability of the angiogram to outline the entire retinal vascular bed. Previous clinical methods of examination of the fundus enabled the phy...
متن کاملAutomated segmentation of foveal avascular zone in fundus fluorescein angiography.
PURPOSE. To describe and evaluate the performance of a computerized automated segmentation technique for use in quantification of the foveal avascular zone (FAZ). METHODS. A computerized technique for automated segmentation of the FAZ using images from fundus fluorescein angiography (FFA) was applied to 26 transit-phase images obtained from patients with various grades of diabetic retinopathy. ...
متن کاملFunages: an Expert System for Fundus Fluorescein Angiography Funages: an Expert System for Fundus Fluorescein Angiography
both the computational and the medical side of these concerns began to develop mutual interests and approaches, and to form coherent col-laborative research [1]. One of the first uses of artificial intelligence (AI) on a practical level was the coupling of expert medical knowledge with computer-based technology. As early as the 1960s, computer scientists and physicians recognized the possibilit...
متن کاملBlood Vessel Segmentation in Retinal Fundus Images
The segmentation of retinal blood vessels in the retina is a critical step in diagnosis of diabetic retinopathy. In this paper, we present a new method for automatically segmenting blood vessels in retinal images. Five basic algorithms for segmenting retinal blood vessels, based on different image processing techniques, are described and their strengths and weaknesses are compared. A hybrid alg...
متن کاملRobust Vessel Segmentation in Fundus Images
One of the most common modalities to examine the human eye is the eye-fundus photograph. The evaluation of fundus photographs is carried out by medical experts during time-consuming visual inspection. Our aim is to accelerate this process using computer aided diagnosis. As a first step, it is necessary to segment structures in the images for tissue differentiation. As the eye is the only organ,...
