Title (EN) IDENTIFYING ABNORMAL TISSUE IN IMAGES OF COMPUTED TOMOGRAPHY
(FR) PROCEDE D'IMAGERIE POUR TOMODENSITOMETRIE ET TOMODENSITOMETRE
Abstract: front page image
(EN)An imaging method for identifying abnormal tissue in the lung is provided, comprising the recording of slice images of the lung by means of X-ray radiation, recording of blood vessels, differentiation of blood vessels and abnormal tissue, segmentation of the abnormal tissue and display of the segmented abnormal tissue on an output device. In addition, a computer tomograph for identifying abnormal tissue in the lung is provided, having a radiation source for recording slice images of the lung and blood vessels by means of X-ray radiation, a computer unit for differentiating the blood vessels from the abnormal tissue and for segmenting the abnormal tissue, as well as an output device for displaying the segmented abnormal tissue. Furthermore, a computer program is provided for controlling a computer tomograph for an identification of abnormal tissue in the lung by means of a radiation source, designed to record slice images of the lung and blood vessels by means of X-ray radiation, to differentiate the blood vessels from abnormal tissue, to segment the abnormal tissue and to control an output device for displaying the abnormal tissue.
(FR)L'invention porte sur un procédé d'imagerie qui permet d'identifier des tissus anormaux dans les poumons, lequel procédé consiste à enregistrer des tranches images du poumon par rayons X, à enregistrer les vaisseaux sanguins, à différencier les vaisseaux sanguins des tissus anormaux, à segmenter les tissus anormaux et à afficher les tissus anormaux segmentés sur un dispositif de sortie. L'invention se rapporte également à un tomodensitomètre permettant d'identifier les tissus anormaux dans le poumon, qui comprend: une source de rayonnement destinée à enregistrer des tranches images du poumon et des vaisseaux sanguins par rayons X; une unité informatique qui permet de différencier les vaisseaux sanguins des tissus anormaux et de segmenter les tissus anormaux; et un dispositif de sortie qui affiche les tissus anormaux segmentés. L'invention comprend en outre un programme informatique qui permet de régler un tomodensitomètre afin qu'il identifie les tissus anormaux dans le poumon à l'aide d'une source de rayonnement, lequel programme est conçu pour enregistrer des tranches images du poumon et des vaisseaux sanguins au moyen de rayons X, pour différencier les vaisseaux sanguins des tissus anormaux, pour segmenter les tissus anormaux et pour commander un dispositif de sortie afin que ce dernier affiche les tissus anormaux.
