Subnanometer optical coherence tomographic vibrography.
The ability to quantify and visualize submicrometer-scale oscillatory motions of objects in three dimensions has a wide range of application in acoustics, materials sciences, and medical imaging. Here we demonstrate that volumetric snapshots of rapid periodic motion can be captured using optical coherence tomography (OCT) with subnanometer-scale motion sensitivity and microsecond-scale temporal...
متن کاملNumerical model of optical coherence tomographic vibrography imaging to estimate corneal biomechanical properties
Most techniques measuring corneal biomechanics in vivo are biased by side factors. We demonstrate the ability of optical coherence tomographic (OCT) vibrography to determine corneal material parameters, while reducing current prevalent restrictions of other techniques (such as intraocular pressure (IOP) and thickness dependency). Modal analysis was performed in a finite-element (FE) model to st...
متن کاملOptical Coherence Tomographic Findings in Berlin’s Edema
PURPOSE To describe optical coherence tomography (OCT) findings in a patient with Berlin's edema following blunt ocular trauma. CASE REPORT A 26-year-old man presented with acute loss of vision in his left eye following blunt trauma. He underwent a complete ophthalmologic examination and OCT. Fundus examination revealed abnormal yellow discoloration in the macula. OCT disclosed thickening of ...
متن کاملSystematic Optimization for Optical Coherence Tomographic Imaging
Optical coherence tomography is a powerful tool that can e ectively provide detail information of biological tissue structure. The axis resolution of optical coherence tomographyhas achieved sub-micrometer andweare interested in its ultrahigh resolution that can be practically utilized for clinical application. In this article, the basic system calibration is discussed; we systematically demons...
متن کاملSwept-Source Optical Coherence Tomographic Findings of Choroidal Osteoma
PURPOSE To report the morphologic features of a choroidal osteoma using swept-source optical coherence tomography (SS-OCT) and fundus autofluorescence (FAF). METHODS Two eyes of two cases with a choroidal osteoma were studied using SS-OCT and FAF. RESULTS The location of the tumor was circumpapillary without macular involvement in case 1 and juxtapapillary with macular involvement in case 2...
