Abstract: Techniques for classifying biomedical image data using a graph neural network are disclosed. In one particular embodiment, the techniques may be realized as a method for classifying biomedical image data comprising generating an annotated representation of biomedical image data; identifying a plurality of pixel clusters based on the biomedical image data; constructing a graph based on the plurality of pixel clusters; determining at least one biomedical feature for at least one node of the graph based on the annotated representation of the biomedical image data; and processing a graph neural network to classify the biomedical image data based on the at least one biomedical feature.

Abstract: Systems and methods for long working distance optical coherence tomography (OCT). According to an aspect, an OCT system includes a reference arm. Further, the OCT system includes a sample arm operably connected to the reference arm. The sample arm includes a scanner configured to scan an optical beam. The sample arm also includes an objective positioned a predetermined distance from the scanner, configured to receive the optical beam, and to direct the optical beam to an object positioned at about the predetermined distance from the scanner for imaging of the object.

Abstract: Systems and methods of optical coherence tomography stereoscopic imaging for microsurgery visualization are disclosed. In accordance with an aspect, a method includes capturing a plurality of cross-sectional images of a subject. The method includes generating a stereoscopic left image and right image of the subject based on the cross-sectional images. Further, the method includes displaying the stereoscopic left image and the right image in a display of a microscope system.

Abstract: Systems and methods for eye tracking for motion corrected ophthalmic optical coherence tomography (OCT) are disclosed. According to an aspect, an imaging system includes an eye tracking device configured to determine movement of an eye. The imaging system also includes an OCT apparatus configured to generate OCT images of a retina of the eye. The OCT apparatus includes a scanner operable to be moved for relocating an OCT scan pivot at a pupil plane for image capture and during capture of the OCT images. The imaging system also includes a controller configured to control the scanner to relocate the OCT scan pivot at the pupil plane based on the determined movement of the eye.

Abstract: Stereoscopic display systems and methods for displaying surgical data and information in a surgical microscope are disclosed herein. According to an aspect, a system includes first and second eyepieces. The system includes a display having first and second display portions, configured to display first images in the first display portion, and configured to display second images in the second display portion.
