michael kors black Friday sale Top of pageThe physics of optical coherence tomographyOCT was first reported by Huang et al. In 1991.34 In vivo retinal imaging was first demonstrated in 1993,35, 36 and early studies in 1995 provided the first demonstration of OCT imaging of the normal retina37 and of macular pathology.13 OCT is the optical analog of ultrasound Bmode imaging (Box 1). With OCT, highresolution crosssectional or threedimensional images of the internal retinal structure are generated by an optical beam being scanned across the retina and the magnitude and echo time delay of backscattered light being measured (Figure 1).Sorry not for me.
