Oscar M. Carrasco-Zevallos has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10973405
    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.
    Type: Grant

  • Publication number: 20210026127
    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.

  • Patent number: 10660519
    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.

  • Patent number: 10238279
    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. The first image and the second image are projected along a first pathway and a second pathway. The system includes a first optical element positioned to relay the first images into the first eyepiece. The system includes a second optical element positioned to relay the second images into the second eyepiece.
