Abstract

"SISTEMA DE AUXìLIO à NAVEGAçãO EM TEMPO REAL PARA DISPOSITIVO DE RADIOGRAFIA". O processo de navegação no meio de uma região de interesse destinado a ser executado em um dispositivo de radiografia (100) do tipo que comporta uma fonte (104) de raios X, meios de registro (103) dispostos em frente à dita fonte e um suporte (105) sobre o qual um objeto (106) a radiografar compreendendo a região de interesse é destinado a ser posicionado, o processo comportando as etapas de a) aquisição de dados tridimensionais de imagens de um volume V1 da região de interesse; b) cálculo, em um instante t, de uma imagem bidimensional de projeção de todo ou parte do volume V1 e/ou de um subvolume do dito volume V1 em função das posições do suporte (105), da fonte (104) e dos meios de registro (103), de um campo visual, de distâncias focal e do objeto; c) superposição ou subtração eventual da imagem de projeção e/ou do subvolume de acordo com um corte plano determinado de uma imagem de radioscopia associada às posições do suporte (105), da fonte (104) e dos meios de registro (103), no campo visual, às distâncias focal e do objeto, no instante t; e d) apresentação em meios de apresentação de uma imagem e/ou de um volume resultante da etapa c), e/ou da imagem de projeção e/ou do subvolume.
