Title (EN) BRAIN IMAGE SEGMENTATION FROM CT DATA
(FR) SEGMENTATION D'IMAGE DU CERVEAU A PARTIR DE DONNEES DE TOMOGRAPHIE ASSISTEE PAR ORDINATEUR (CT)
Abstract: front page image
(EN)The brain structure is extracted from CT data based on thresholding and brain mask propagation. Two thresholds are determined: a high threshold excludes the high intensity bones, while a low threshold excludes air and CSF. Brain mask propagation uses the spatial relevance of brain tissues in neighbouring slices to exclude non-brain tissues with similar intensities.
(FR)Selon l'invention, la structure du cerveau est extraite de données CT, sur la base du seuillage et de la propagation du masque cérébral. Deux seuils sont déterminés: un seuil élevé qui exclue les os à intensité élevée, un seuil bas excluant l'air et le liquide céphalo-rachidien. La propagation du masque cérébral fait appel à la pertinence spatiale des tissus cérébraux dans des tranches adjacentes, afin d'exclure des tissus non cérébraux à intensités similaires.
