3D RETINAL DISRUPTIONS DETECTION USING OPTICAL COHERENCE TOMOGRAPHY
First Claim
1. An imaging apparatus, comprising:
- an optical source;
an x-y scanner receiving light from the optical source and directing it onto a sample;
a detector receiving reflected light from the scanner; and
a computer receiving a signal from the detector and executing code stored in a memory, the code providing instructions forproviding a 3D data set containing voxels of a sample,identifying one or more 3D seeds from the 3D data set,obtaining characteristics of 3D disruptions based on the 3D seeds;
generating measurements for the 3D disruptions; and
displaying the results of the 3D disruptions.

Abstract
System and method for 3D retinal disruption/elevation detection, measurement and presentation using Optical Coherence Tomography (OCT) are provided. The present invention is capable of detecting and measuring the abnormal changes of retinal layers (retinal disruptions), caused by retinal diseases, such as hard drusen, soft drusen, Pigment Epithelium Detachment (PED), Choroidal Neovascularization (CNV), Geographic Atrophy (GA), intra retinal fluid space, and exudates etc. The presentations of the results are provided with quantitative measurements of disruptions in retina and can be used for diagnosis and treatment of retinal diseases.
