Abstract
The present disclosure describes a system and method to classify optical coherence tomography (OCT) images. The present system can classify OCT images without first segmenting the retina tissue. The system can generate one or more profiles from vertical transects through the OCT images. The system can identify image statistics based on the one or more profiles. The system's classifier can then classify the OCT images based on the identified image statistics.
Claims18
A system comprising one or more processors and a memory storing processor executable instructions, wherein execution of the instructions stored in the memory cause the one or more processors to:
- retrieve, from the memory, an optical coherence tomography (OCT) image of retina tissue;
- determine a location of a fovea in the OCT image;
- identify a transect from the OCT image a predetermined distance from the location of the fovea, wherein the transect comprises an array of intensity values through the retina tissue of the OCT image;
- generate a profile for the transect, the profile for the transect comprising at least one statistic of the array of intensity values;
- and
- classify the OCT image using the profile for the transect into one of a wet age-related macular degeneration (AMD) group, a dry AMD group, or a healthy group.
A method comprising:

- determining a location of a fovea in the OCT image;
- identifying a transect from the OCT image a predetermined distance from the location of the fovea, wherein the transect comprises an array of intensity values through the retina tissue of the OCT image;
- generating a profile for the transect, the profile for the transect comprising at least one statistic of the array of intensity values;
- and
- classifying the OCT image using the profile for the transect into one of a wet age-related macular degeneration (AMD) group, a dry AMD group, or a healthy group.
