Patent Images
1. An intraocular imaging method comprising:
- receiving image data representing image information of an ocular system from a plurality of images having a corresponding plurality of depth ranges, wherein at least two of the plurality of depth ranges overlap;
identifying a portion of at least one image that overlaps with a portion of at least one other image;
cropping said portion of at least one image; and
generating a composite image from the remainder of the plurality of images;
wherein at least one of the plurality of images is a subsurface image; and
wherein generating a composite image comprises forming from the image data a single image for the overlapping portion of the depth ranges.

Abstract
Systems, methods and apparatuses for an intraocular imaging system are disclosed comprising an optical coherence tomography (OCT) system. The OCT system has an imaging range that may enable substantial portions of an eye or even a whole eye to be imaged. The OCT system may be coupled to an operation microscope, such that, for example, a surgeon can visualize ocular structures like the human crystalline lens and other ocular structures such as the cornea and/or vitreous while surgical instruments are in the field of view.

9. An intraocular imaging system comprising:
-
imaging optics configured to obtain a plurality of images at a corresponding plurality of imaging ranges, at least two of the plurality of imaging ranges overlapping; image processor circuitry configured in at least one of hardware and software to receive and process images to form, from the received plurality of images, a composite image comprising a single image for the overlapping portion of the imaging ranges; wherein said single image is obtained by identifying a portion of at least one image corresponding to an overlapping depth range and cropping said portion; and wherein at least one of the plurality of images is a subsurface image. - View Dependent Claims (10, 11, 12)
