Abstract

"DISPOSITIVO PARA A DETECçãO E CARACTERIZAçãO DE TECIDO BIOLóGICO". A invenção se refere a um método para detectar e localizar a diferença em densidade e/ou estrutura e/ou composição química de um tecido biológico (7) que é submetido a iluminação contínua em uma primeira faixa determinada de freqüências, capaz de fazer com que o tecido gere um fenómeno de fluorescência, auto-fluorescência ou luminescância em uma segunda faixa de freqüências. Referido método é caracterizado pelo fato de compreender as etapas de: o tecido biológico iluminado desse modo é visualmente capturado por meio de vídeo de cor provido com sensores de imagem com um mosaico de pixéis provido com filtros de cores complementares; para cada ponto da imagem assim obtido 1) informação relacionada à energia recebida por cada pixel é coletada de modo a reconstituir uma imagem do tecido biológico (7); b) amplificação ocorre para o sinal correspondente à energia recebida na segunda faixa de freqüências, de modo a caracterizar ou fazer com que apareça a referida diferença do tecido biológico (7) na imagem assim obtida.
