International Classification:

A61B 314

US Classification:

351206

Abstract:

The invention is a method and system for mosaicing images of the eye to create high resolution, wide-field ophthalmic images for the diagnosis and treatment of eye diseases. The inventive method acquires a first image of the eye, acquires a second image of the eye, and processes the images to produce a mosaic representation. The second image includes a portion of the first image. To guide in acquiring the second image, the method may view the first image while acquiring the second image. The images typically are acquired using either a direct ophthalmoscope or a slitlamp biomicroscope. The method further may convert the images to a digital format. The step of processing includes aligning and merging the images, and conducting real-time processing and non-real-time processing. Real-time processing may include eliminating non-overlapping images, image registration, topology inference, local-to-global alignment, image fusion, signal estimation, and multiresolution blending, while the non-real-time processing may include local alignment, global alignment, image registration, intra-alignment, inter-alignment, signal averaging, and photometric blending.

International Classification:

A61B003/00

US Classification:

351/200000

Abstract:

The invention includes a computer-implemented method, system (), and computer-readable medium having computer-executable modules for judging changes in components of an eye. The inventive computer-implemented method includes the steps of acquiring (), displaying (), and superimposing at least two digital images of the components of the eye. The method further includes the step of processing at least one of the digital images such that the superimposed images may be compared, and the step of flickering among the superimposed digital images. The step of acquiring the images may include the step of converting a photographic representation of the components of the eye to the digital image. The step of processing may include registering, warping, and/or aligning the digital images.

International Classification:

US Classification:

351206

Abstract:

An ophthalmic augmented reality environment is developed in order to allow for (a) more precise laser treatment for ophthalmic diseases, (b) teaching, (c) telemedicine, and (d) real-time image measurement, analysis, and comparison. A preferred embodiment of the system is designed around a standard slit-lamp biomicroscope. The microscope is interfaced to a CCD camera, and the image is sent to a video capture board. A single computer workstation coordinates image capture, registration, and display. The captured image is registered with previously stored, montaged photographic and/or angiographic data, with superposition facilitated by fundus-landmark-based fast registration algorithms. The computer then drives a high intensity, VGA resolution video display with adjustable brightness and contrast attached to one of the oculars of the slit-lamp biomicroscope.
