Abstract

processo de exame radiossintético de espécimes. a presente invenção refere-se a um processo de exame não destrutivo em contínuo de espécimes dito de radiossíntese, integrável no processo de gestão do ciclo de vida desses espécimes. esse processo funciona por meio de pelo menos uma fonte de raio x e de pelo menos um captador numérico formando par com essa fonte, fonte e captador deslocando-se em trajetórias e opostas e homotéticas no interior de um espaço de movimento, para cada geração em tempo real de pelo menos um corte de cada espécime.
