Abstract

Patente de Invenção: "MéTODO E APARELHO PARA REALIZAR ANGIOGRAFIA INTRA-OPERATIVA". Trata-se de um dispositivo que é proporcionado com um laser (1) para excitar o agente de formação de imagem fluorescente que emite radiação a um comprimento de onda que faz com que qualquer dos agentes localizados dentro da vasculatura ou tecido de interesse (3) irradiado, emita radiação de um comprimento de onda particular. Vantajosamente, uma câmera capaz de obter múltiplas imagens em um período de tempo, tal como uma câmera CCD (2) pode ser usada para capturar a emissão do agente de formação de imagem. Um filtro de passagem de banda (6) impede a captura de radiação outra que não aquela emitida pelo agente de formação de imagem. Um sensor de distância (9) incorpora um visor (9a) que proporciona retorno ao médico, dizendo que o laser está localizado a uma distância do vaso de interesse que é ótima para a captura de imagens de alta qualidade.
