Simultaneous acquisition of sectional and fundus ophthalmic images with spectral-domain optical coherence tomography

Abstract: A high-speed spectral-domain optical coherence tomography (OCT) system was built to image the human retina in vivo. A fundus image similar to the intensity image produced by a scanning laser ophthalmoscope (SLO) was generated from the same spectra that were used for generating the OCT sectional images immediately after the spectra were collected. This function offers perfect spatial registration between the sectional OCT images and the fundus image, which is desired in ophthalmology for monitoring data quality… Show more

“…The high image acquisition speeds afforded by the Fourier domain instruments enable the generation of highdefinition OCT images with increased numbers of transverse pixels and improved coverage of the retina, as well as the acquisition of 3-dimensional OCT (3D-OCT) data sets. 3D-OCT imaging is especially promising because projection image data can be summed to provide a virtual fundus image, which enables precise and reproducible registration of individual OCT images to fundus features [68,69]. Taken together, these features promise to improve the reproducibility of RNFL thickness measurements and other morphometric measurements.…”

“…This image, called the sum voxel projection (SVP), is especially useful for scan orientation and localization of retinal structures or pathologic features (Figure 2, Top). 10,11 Moreover, the retinal vessel pattern manifested on the SVP is a good measure for evaluating the 3D imaging quality. For example, motion artifacts in a volumetric imaging experiment often will result in broken or jagged blood vessel representation on the SVP.…”

“…This OCT fundus image (OFI) is generated by summing the signal of each of the A-scans and viewing their relative values en face. 14,21,22 It is this en face OFI that results in the visualization of GA as a bright area on the image due to the increased penetration of light into the choroid where atrophy has occurred in the macula. The increased OCT choroidal signal associated with GA results in the GA appearing brighter on the en face OFI compared with the surrounding areas because the absence of the RPE and choriocapillaris in GA results in more light penetrating the choroid and being reflected back to the detector compared with the light scattering that occurs with an intact RPE in the surrounding areas.…”
