Abstract

método e sistema para a formação de imagem radiográfica por varredura esteroscópica binocular. em um método de formação de imagem radiográfica por varredura estereoscópica binocular, os raios-x emitidos pela mesma fonte de radiação são utilizados. os raios-x passam através de um colimador de corte duplo para formar dois setores de feixes de raios-x, os quais são simétricos ou assimétricos e possuem um ângulo entre eles. os setores de feixes de raios-x , após a penetração através do objeto sob detecção, são recebidos pelo arranj o de detector esquerdo e direito , respectivamente , e então são convertidos em sinais elétricos para serem lançados no respectivo sistema de aquisição de imagem, e recebidos por um sistema de processamento computacional para processamento e exibição da imagem. um sistema corresponde nte ao método compreende uma fonte de radiação, um controlador de feixe , dois braços mutuamente conectados do arranjo do detector, s istemas d e aquisição de imagem conectados respectivamente a cada arranjo de detector e um sistema de processamento computacional. a presente invenção pode exibir as imagens de transmissão detectadas por cada uma das dispos ições de detector, bem como pelos t omogramas com diferentes profundidades reconstruídos a partir das imagens de transmissão, de acordo com o princípio da paralaxe . a presente invenção é conveniente , rápida na detecção e permitir o reconhecimento de ob jetos em diferentes profundidades com baixo custo .
