Method For Finding The Lateral Position Of The Fovea In An Sdoct Image Volume

View page
US Patent:
8251511, Aug 28, 2012
Filed:
Nov 18, 2011
Appl. No.:
13/299962
Inventors:
Paul F. Stetson - Piedmont CA,
Homayoun Bagherinia - San Francisco CA,
Assignee:
Carl Zeiss Meditec, Inc. - Dublin CA
International Classification:
A61B 3/00
A61B 3/10
US Classification:
351246, 351205
Abstract:
Embodiments of the present invention provide methods for finding the lateral position of the fovea in an OCT image volume. In one instance, a cost function is developed whose minimum is located at or near the foveal center. This cost function includes one or more measures of retinal layer thickness and/or measures of distance from blood vessels or a priori locations.

US Patent:
20090268162, Oct 29, 2009
Filed:
Mar 31, 2009
Appl. No.:
12/415976
Inventors:
Paul F. STETSON - Piedmont CA,
Homayoun BAGHERINIA - San Francisco CA,
Assignee:
Carl Zeiss Meditec, Inc. - Dublin CA
International Classification:
A61B 3/14
US Classification:
351246
Abstract:
Embodiments of the present invention provide methods for finding the lateral position of the fovea in an OCT image volume. In one instance, a cost function is developed whose minimum is located at or near the foveal center. This cost function includes one or more measures of retinal layer thickness and/or measures of distance from blood vessels or a priori locations.

Segmentation And Enhanced Visualization Techniques For Full-Range Fourier Domain Optical Coherence Tomography

View page
US Patent:
20130208240, Aug 15, 2013
Filed:
Feb 7, 2013
Appl. No.:
13/761404
Inventors:
Homayoun BAGHERINIA - Oakland CA,
Assignee:
Carl Zeiss Meditec, Inc. - Dublin CA
International Classification:
A61B 3/10
G01B 9/02
US Classification:
351206, 356479, 351246
Abstract:
Presented here are new processing techniques for optical coherence tomography (OCT) data that allow for improved visualization and use of full-range OCT images. These techniques minimize the central line artifact and the complex conjugate artifact without requiring additional system hardware or significantly increasing post-processing time. The central line artifact is minimized by normalizing each A-scan to account for ripples at the zero-delay position. The complex conjugate artifact is minimized by segmentation of a layer or layers that cross the zero-delay position, and in some embodiments by further segmentation of other surfaces based on the segmentation of the initial layer or layers. The segmentation information is then used to selectively attenuate the complex conjugate image. It may also be used for other purposes, such as dewarping.

Differential Geometric Metrics Characterizing Optical Coherence Tomography Data

US Patent:
20140029820, Jan 30, 2014
Filed:
Jan 18, 2013
Appl. No.:
13/744911
Inventors:
Homayoun BAGHERINIA - Oakland CA,
Assignee:
CARL ZEISS MEDITEC, INC. - Dublin CA
International Classification:
A61B 3/10
US Classification:
382131
Abstract:
A method is disclosed for analyzing 3D image data generated from optical coherence tomography (OCT) systems. The first step in the method is to identify one or more surfaces within the 3D data set. The surfaces are then characterized using geometric primitives. Geometric primitives such as concavities, convexities, planar parts, saddles, and crevices can be used. In a preferred embodiment, the primitives are combined. Various pathological conditions of the eye can be evaluated based on any analysis of the primitives.
