Embodiment Construction

[0011] Optical coherence tomography (OCT) is a technique for performing high-resolution cross-sectional imaging that can provide images of micron-scale tissue structures in situ and in real time. OCT is an interferometry method that determines the scattering profile of a sample along an OCT beam. Each scatter profile is called an axial scan, or A-scan. Cross-sectional images (B-scans) and extended 3D volumes are constructed from many A-scans in which the OCT beam is moved to a set of lateral positions on the sample.

[0012] In time-domain OCT (TD-OCT), optical delay lines are used for mechanical depth scanning at relatively slow imaging speeds. In frequency-domain OCT (FD-OCT), the interference signal between the reference light and the backscattered light from the sampling point is recorded in the frequency domain instead of the time domain. After wavelength calibration, a one-dimensional Fourier transform is performed to obtain the A-line spatial distribution of the objec...

Abstract

An improved workflow for acquiring image data of the eye of a patient is described. The workflow can be used with any ophthalmic diagnostic devices including an optical coherence tomography (OCT) device. This workflow is referred herein as a report driven workflow. Under the report driven workflow, a plurality of report options are presented to the device operator. These report options are selectable to generate a report summarizing analysis relating to a specific pathology or region of the eye. A desired report option is selected by the device operator. Based on the selected report option, one or more scan types are automatically selected by the device software. Image data corresponding to the one or more scan types are captured using the ophthalmic diagnostic device. An analysis for theselected desired report option is generated based on the captured image data and is then presented to the device operator.

Description

technical field [0001] The present application relates to the acquisition of ophthalmic image data of a patient using an improved workflow, and more particularly to a system and method for acquiring and displaying a series of ophthalmic image data of a patient's eye using a report-driven workflow. Background technique [0002] In commercially available ophthalmic diagnostic systems, an instrument operator typically selects from a range of scan options based on known eye locations that may be associated with a particular pathology. When performing scans with these ophthalmic diagnostic systems, especially optical coherence tomography (OCT) systems, instrument operators spend a great deal of time selecting the appropriate scan type and then creating reports summarizing the results. This process or workflow is time consuming and sometimes leads novice operators to choose the wrong type of scan.
