O filtro dinâmico otimizado (Enhanced Dynamic Wedge, EDW) utiliza o movimento do colimador para fazer o efeito de filtro, diminuindo o tempo de tratamento em relação ao filtro físico. Para validação do sistema foram feitas algumas comparações entre dados medidos e calculados pelo sistema de planejamento tais como: fluência de perfil de feixe; planos de tratamentos, utilizando a análise gama; Fator Filtro; e PDP. Os resultados da análise gama da comparação de fluência, tanto de perfil de feixe quanto para planos de tratamentos, foram entre 96% à 100% respectivamente, e, de Fator Filtro e PDP, a diferença máxima é de 1,9%. Assim os resultados se mostraram satisfatóriosDownloads
