Abstract

radiografia 3d rápida usando múltiplas fontes de raios x pulsadas em movimento com braço em c. a presente invenção refere-se a um sistema de imagem de raios x de braço em c usando múltiplas fontes de raios x pulsadas em movimento para realizar radiografia 3d eficiente e ultrarrápida. fontes de raios x montadas em uma estrutura em movimento para formar uma matriz. as fontes de raios x movem-se simultaneamente em relação a um objeto em uma trilha de arco predefinida a uma velocidade constante como um grupo. cada fonte individual também pode se mover rapidamente em torno de sua posição estática em uma pequena distância. quando uma fonte tem uma velocidade igual à velocidade do grupo, mas com direção de movimento oposta, a fonte em uma extremidade do braço em c e o detector de painel plano de raios x na outra extremidade do braço em c são ativados através de uma unidade de controle de exposição externa para que a fonte fique momentaneamente parada. o braço em c fornece imagens de digitalização de raios x 3d em um amplo ângulo de varredura e em diferentes posições por rotação. a imagem de raios x pode ser analisada por um módulo de inteligência artificial para diagnóstico em tempo real.
