The scan protocol used in this study was the Fast Macular Thickness program, which produced retinal mapping consisting of 6 radiating cross-sectional scans, each 6 mm length that produced a circular plot where the fovea become a central zone of 1mm diameter. The superior, nasal, inferior, and...
Optical coherence tomography angiography (OCTA) is a relatively new imaging technique that provides more advanced photos of the retina. OCTA is derived from OCT technology. An OCTA scan provides just as much information as OCT, but with more advanced, three-dimensional images. ...
3.8. The cSLO image is used to position the selected OCT scan pattern, which is displayed superimposed on the fundus image (green line in Fig. 3.8). Active eye tracking (TruTrack™) then locks the scan to this position during the acquisition. This is accomplished by an algorithm that ...
Let (x,y) be an input B-scan image and\(y\in \{1,\ldots ,K\}\)the corresponding OCT class label. The inlier dataset\(\mathscr {D}^{in}\)is composed of the central B-scans from normal, iAMD, nAMD and GA OCT volumes. The near-outlier dataset\(\mathscr {D}^{out}_{near}\...
