Abstract

técnicas de geração de imagem ocular multimodal e aparelho. aspectos da presente invenção fornecem técnicas aperfeiçoadas para geração de imagem do fundo de retina de um indivíduo. alguns aspectos referem-se a um aparelho de geração de imagem que pode ser de formato substancialmente binocular e/ou pode alojar múltiplos dispositivos de geração de imagem configurados para fornecer múltiplos modos correspondentes de gerar imagem do fundo de retina do indivíduo. alguns aspectos referem-se a técnicas para gerar imagem do olho de um indivíduo usando luz branca, fluorescência, infravermelho (iv), tomografia de coerência ótica (oct), e/ou outras modalidades de geração de imagem que podem ser empregadas pelo aparelho de geração de imagem único. alguns aspectos referem-se a aperfeiçoamentos em tecnologias de geração de imagem de luz branca, fluorescência, iv, oct e/ou outras que podem ser empregadas sozinhas ou em combinação com outras técnicas. alguns aspectos referem-se a técnicas de geração de imagem multimodal que permitem a determinação de um estado de saúde do indivíduo. aparelhos de geração de imagem e técnicas descritos aqui, fornecem imagens de fundo de retina de grau médico e podem ser produzidos ou conduzidos a baixo custo, aumentando assim o acesso à geração de imagem de grau médico.multimodal ocular imaging techniques and apparatus. Aspects of the present invention provide improved techniques for imaging the fundus of a subject's retina. some aspects pertain to an imaging apparatus which may be substantially binocular in shape and/or may house multiple imaging devices configured to provide corresponding multiple ways of imaging the fundus of the subject's retina. some aspects relate to techniques for imaging an individual's eye using white light, fluorescence, infrared (iv), optical coherence tomography (oct), and/or other imaging modalities that may be employed by the imaging device. single image generation. some aspects refer to improvements in white light, fluorescence, iv, oct and/or other imaging technologies that can be employed alone or in combination with other techniques. some aspects refer to multimodal image generation techniques that allow the determination of an individual's health status. imaging apparatus and techniques described herein provide medical grade retinal fundus images and can be produced or conducted at low cost, thus increasing access to medical grade imaging.
