Embodiment Construction

[0029] Optical coherence tomography (OCT) techniques have been commonly used in the medical industry to obtain information-rich content in three-dimensional (3D) data sets. OCT can be used to provide imaging to catheter stylets during surgical procedures. In the dental industry, OCT has been used to guide dental procedures. In the field of ophthalmology, OCT can produce accurate and high-resolution 3D data sets, which can be used to detect and monitor different eye diseases in the cornea and retina. Different scanning configurations have been developed for different industries and different clinical applications. For example, scanning configurations have been designed to acquire information in ganglion cell complexes (GCCs) (see US Patent Application Publication 2008 / 0309881). GCC has been demonstrated to provide precise information useful for the clinical diagnosis of glaucoma disease (see Tan O. et al. [Ophthalmology, 116:2305-2314 (2009)]). Other useful scanning configur...

Abstract

In accordance with some embodiments, a method of eye examination includes acquiring OCT data with a scan pattern centered on an eye cornea that includes n radial scans repeated r times, c circular scans repeated r times, and n* raster scans where the scan pattern is repeated m times, where each scan includes a A-scans, and where n is an integer that is 0 or greater, r is an integer that is 1 or greater, c is an integer that is 0 or greater, n* is an integer that is 0 or greater, m is an integer that is 1 or greater, and a is an integer greater than 1, the values of n, r, c, n*, and m being chosen to provide OCT data for a target measurement, and processing the OCT data to obtain the target measurement.

Description

[0001] related application [0002] This application claims priority to U.S. Provisional Application No. 61 / 419,800, filed December 3, 2010, and U.S. Nonprovisional Application No. 13 / 310,626, filed December 3, 2011, the entire contents of which are hereby incorporated by reference . technical field [0003] Embodiments described herein relate generally to methods and systems for collecting and processing images in ophthalmology for the diagnosis and treatment of disease or any other physiological condition. Background technique [0004] Optical coherence tomography (OTC) is an optical signal imaging and processing technique that captures three-dimensional (3D) data sets with micrometer resolution. Over the past fifteen years, this OCT imaging modality has been commonly used for non-invasive imaging of objects of interest, such as the retina of the human eye. Cross-sectional retinal images as a result of OCT scans allow users and clinicians to assess various visual conditi...
