P 346 Reproducibility and error sources in automatic diameter measurement of retinal branch vessels
نویسندگان
چکیده
Methods A measuring ophthalmoscope based on the Zeiss retina camera RC 310 is coupled with a CCD device. A frame grabber digitizes the picture section with the interesting vessel segments. An adaptive algorithm recognizes the position and direction of the vessels automatically and calculates the vessel diameters. Other measuring data are recorded additionally, for example the R spike of the electrocardiogram. This additional information can be used for the measurement of the pulsating changes of the vessel diameter.

Automatic Optic Disc Center and Boundary Detection in Color Fundus Images
Accurately detection of retinal landmarks, like optic disc, is an important step in the computer aided diagnosis frameworks. This paper presents an efficient method for automatic detection of the optic disc’s center and estimating its boundary. The center and initial diameter of optic disc are estimated by employing an ANN classifier. The ANN classifier employs visual features of vessels and th...
متن کاملImprovement of reproducibility of macular volume measurements using the Heidelberg retinal tomograph.
AIMS To develop a more reproducible method of macular volumetric analysis in order to facilitate serial monitoring of changes in retinal oedema with time. METHODS The Heidelberg retinal tomography (HRT) machine was used to scan the macula of 20 normal subjects and 40 diabetics with macular oedema. The volume above reference plane (VARP) within a 2 mm diameter and 3 mm diameter circle was meas...

متن کاملAutomatic retinal oximetry.
PURPOSE To measure hemoglobin oxygen saturation (SO(2)) in retinal vessels and to test the reproducibility and sensitivity of an automatic spectrophotometric oximeter. METHODS Specialized software automatically identifies the retinal blood vessels on fundus images, which are obtained with four different wavelengths of light. The software calculates optical density ratios (ODRs) for each vesse...
متن کاملThe diameter of the human retinal branch vessels does not change in darkness
In the main part of our study we examined the changes of the retinal branch vessel diameters during dark and light adaptation. We used a "hybrid" technique, using the newly developed Retinal Vessel Analyzer (RVA) to analyze recordings of images made with a scanning laser ophthalmoscope (SLO) employing near-infrared illumination. Since there have been no previous reports of using SLO data with t...
