Abstract

métodos para formar imagem de um olho e para formar imagem de um objeto, e, sistemas de formação de imagem de laser cirúrgico. técnicas e sistemas de formação de imagem óptica proveem formação de imagem óptica de alta fidelidade baseada em formação de imagem tomográfica de coerência óptica e podem ser usadas formação de imagem óptica em cirurgia oftálmica cirurgia guiada por formação de imagem. um método para formar imagem de um olho inclui posicionar o olho relativo a um sistema de formação de imagem tomográfica de coerência óptica de domínio espectral (sd-oct), o olho tendo uma primeira e segunda estruturas, e formar imagem do olho com o sistema de formação de imagem de sd-oct selecionando uma de uma imagem direta e uma invertida da primeira estrutura de olho e gerar uma primeira porção de imagem correspondendo à imagem selecionada da primeira porção de imagem correspondendo à imagem selecionada da primeeira estrutura de olho, selecionando uma de uma imagem direta e uma invertida da segunda estrutura de olho e gerando uma primeira porção de imagem correspondendo á imagem selecionada da segunda estrutura, e suprimindo as imagens não selecionadas das primeira e segunda estruturas.
