Abstract

COLETOR DE IMAGEM DIGITAL PARA SISTEMAS RAIO-X; SISTEMA DE MEDIçãO DE AUTO-EXPOSIçãO PARA UM COLETOR DE IMAGEM DIGITAL DE RAIO-X E PARA OBTENçãO DE IMAGENS DE MATERIAIS. Um sistema digital Raio-X para capturar imagens com alta qualidade pelo aumento máximo de coleta de luz emitida de uma tela intensificadora em resposta ao impacto do Raio-X. O sistema digital Raio-X inclui um alojamento tendo uma tela intensificadora fluorescente para receber os Raios-X emitidos, dois refletores para maximizar a coleta de luz otimizando o caminho da luz a partir da tela intensificadora e de um conjunto de lentes. Um chip CCD recebe a luz do conjunto de lentes, para prover uma imagem digital para imediato processador de com placa-mãe ou um pós-processador por computador. O alojamento é compacto, e poderá ser usado como uma reposição direta para tradicionais rolos de filmes sem maiores modificações ao sistema. O conjunto de lentes inclui lentes de formato livres igualadas para remover distorções óticas, e o alojamento incluindo um sensor de luz para prover medição de exposição e realimentação. O sistema é designado para ser quase-monocromático para manter consistente qualidade de imagem sobre a inteira área da tela intensificadora.
