Embodiment Construction

[0018] Optical coherence tomography (OCT) is a technique for performing high-resolution cross-sectional imaging that can provide images of tissue structures at the micrometer scale both in situ and in real time [15]. OCT is an interferometry method that determines the scattering profile of a sample along an OCT beam. Each scattering profile is called an axial scan or A-scan. The cross-sectional image (B-scan) is composed of many A-scans by augmenting the 3D volume, where the OCT beam is moved to a set of lateral positions on the sample. OCT provides a mechanism for micrometer resolution measurements.

[0019] In frequency-domain OCT (FD-OCT), the interference signal between the reference light and the backscattered light at the sample point is recorded in the frequency domain instead of the time domain. After wavelength calibration, a one-dimensional Fourier transform is employed to obtain the A-line spatial distribution of the object scattering barrier. Spectroscopy within...

Abstract

Improvements to user interfaces for ophthalmic imaging systems, in particular Optical Coherence Tomography (OCT) systems are described to improve how diagnostic data are displayed, analyzed and presented to the user. The improvements include user customization of display and reports, protocol driven work flow, bookmarking of particular B-scans, accessing information from a reference library, customized normative databases, and ordering of follow-up scans directly from a review screen. A further aspect is the ability to optimize the contrast and quality of displayed B-scans using a single control parameter. Virtual real time z-tracking is described that maintains displayed data in the same depth location regardless of motion.

Description

[0001] priority [0002] This application claims priority to US Provisional Application Serial No. 61 / 785,347, filed March 14, 2013, the contents of which are incorporated herein by reference. technical field [0003] The present invention relates to ophthalmic diagnostic testing and imaging, and more particularly to user interface improvements for acquiring, displaying, and analyzing ophthalmic diagnostic data. Background technique [0004] The field of ophthalmic diagnostics includes imaging-based techniques or structural and functional approaches for diagnosing and monitoring various pathologies of the eye. One pathology of concern is glaucoma, a form of optic neuropathy that causes characteristic visual field defects. This is caused by damage to the optic nerve (ON) and retinal ganglion cells (RGC) and their axons, the retinal nerve fiber layer. Investigating the relationship between the development of functional impairment in the visual field and the structural glauco...
