Abstract

SISTEMA PARA FORNECER RADIOGRAFIA 3D RÁPIDA COM O USO DE MÚLTIPLAS FONTES DE RAIOS X PULSADOS EM MOVIMENTO E MÉTODO DE RADIOGRAFIA 3D RÁPIDA COM O USO DE MÚLTIPLAS FONTES DE RAIOS X PULSADOS EM MOVIMENTO. Trata-se um sistema de imagiologia de raios X que usa múltiplas fontes de raios X pulsados em movimento para realizar radiografia 3D altamente eficaz e ultrarrápida. Há múltiplas fontes de raios X pulsados montadas em uma estrutura em movimento para formar um arranjo de fontes. As múltiplas fontes de raios X se movem simultaneamente em relação a um objeto em um trilho em arco predefinido a uma velocidade constante como um grupo. Cada fonte de raios X individual pode também se mover rapidamente ao redor de sua posição estática em uma pequena distância. Quando uma fonte de raios X tem uma velocidade que é igual à velocidade do grupo, mas com direção de movimento oposta, a fonte de raios X e o detector de painel plano de raios X são ativados através de uma unidade de controle de exposição externa de modo que a fonte permaneça momentaneamente estacionária. Isso resulta em uma distância de percurso bastante reduzida para cada fonte de raios X. A varredura 3D pode cobrir um ângulo de varredura muito mais amplo em um tempo muito mais curto, e a análise de imagem pode também ser feita em tempo real.
