Abstract

digitalizações progressivas com sistema de imagem de tomossíntese de múltiplas fontes em movimento de raios x pulsadas. a presente invenção refere-se ao sistema e ao método que são divulgados para aquisição de imagens a partir de digitalizações parciais esparsas de grande angular distribuídas. durante a reconstrução da imagem em tempo real, a inteligência artificial (ia) determina se há informações suficientes para realizar diagnósticos com base nas digitalizações iniciais. se houver informações suficientes nas digitalizações fracionárias, a aquisição de dados será interrompida; se forem necessárias mais informações, o sistema executa outra rodada de digitalizações esparsas de ângulo ampliado em um novo local progressivamente até que o resultado seja satisfatório. o sistema reduz a dose de raios x em um paciente e executa uma digitalização mais rápida de raios x em sistemas de imagens de tomossíntese com múltiplas fontes em movimento pulsadas. o método e o sistema também reduzem significativamente o tempo necessário para exibir imagens de tomossíntese tridimensionais de alta qualidade.
