Abstract

resumo sistema de imageamento e método a presente invenção refere-se a um sistema de imageamento (300) que inclui uma fonte de radiação (308) que emite radiação que atravessa, em uma direção, uma região de exame (306) durante uma varredura, e uma matriz detectora (316) localizada em posição oposta à fonte de radiação, do outro lado da região de exame, que detecta a radiação que atravessa a região de exame durante uma varredura e produz um sinal indicativo da mesma. um conformador de feixe (318), localizado entre a fonte de radiação e a região de exame, define um perfil de intensidade de fluxo do feixe de radiação que atravessa a região de exame o conformador de feixe inclui uma pluralidade de elementos atenuantes de raios x (326), que atenuam os raios x incidentes sobre o mesmo, intercalados com uma pluralidade de regiões isentas de material nas quais passam raios x não atenuados. uma transmitância dos raios x é maior em um ponto mais próximo a uma região central do conformador de feixe em relação às regiões de extremidade do conformador de feixe. um movimentador do conformador de feixe (328) translada o conformador de feixe durante pelo menos um intervalo de captura da varredura. 1/1
