Some embodiments of the present invention may relate to a device and a method of enabling an automatic global matching of a plurality of images to provide a substantially consistent planar representation of a fundus. According to some embodiments of the invention, a device for enabling an automatic global matching of a plurality of images to provide a substantially consistent planar representation of a fundus may include a local matching module and a global matching module. The local matching module may be adapted to locally match a pair of overlapping images. As part of locally matching the images, the local matching module may be adapted to provide a best offset vector for the images based upon a matching of features from overlapping portions of the images. The global matching module may be adapted to globally match at least a triplet of locally matching pairs of images whose best offset vector sum is substantially zero.

Device, method and system for automatic montage of segmented retinal images

A system and method are presented for use in imaging the patient's retina. A light source unit is provided including a light emitting diode (LED) arrangement comprising multiple LEDs of different wavelength ranges. A light guide arrangement is used with the LEDs arrangement and is configured for coupling light from the LEDs and providing output light beams of a desired shape. The illuminating light is directed towards a region on the retina, and light returned from the illuminated region is collected and directed to an image detector unit. The invention enables the use of LED light at high intensity as required in the eye retina imaging, while maintaining the required high-quality imaging. Also, the invention provides for simultaneous or quasi-simultaneous as well as high-speed imaging in FA and ICG imaging procedures, thereby satisfying a long felt need in ophthalmology. Also, the invention provides for automated illumination or light exposure control to optimize overall light exposure to the patient eye and best acquired image quality in terms of brightness, contrast and image signal-to-noise ratio.

Integrated retinal imager and method

Some embodiments of the present invention may relate to a device and a method of enabling the stabilization of a series of retinal angiography images to provide a coherent serial display, the method comprising: locally matching a pair of overlapping images, said locally matching includes at least providing a best offset vector for the images, wherein the best offset vector is provided based upon a matching of features from overlapping portions of the images; globally matching at least a triplet of matching pairs of images, wherein pairs of globally matching images include locally matching pairs whose best offset vector sum is substantially zero; choosing a key image; and aligning all the remaining images to the key image.
