Abstract
(EN)
The present invention relates to a method for estimating a measure of a penumbra size of a penumbra in biological tissue wherein first and second images obtained respectively by perfusion weighted imaging (PWI) and diffusion weighted imaging (DWI) are analyzed, and wherein the analysis of the first image includes application of a level set method, and the analysis of the second image includes application of a grayscale morphological operation. In a further embodiment of the invention, a connected component labeling algorithm maybe applied on any one of the first and second image. The invention further relates to a system, a computer program product and use of a corresponding method.
(FR)
La présente invention porte sur un procédé d'estimation d'une mesure d'une taille de pénombre d'une pénombre dans un tissu biologique, procédé suivant lequel des première et seconde images obtenues respectivement par imagerie pondérée en perfusion (PWI) et imagerie pondérée en diffusion (DWI) sont analysées, et suivant lequel l'analyse de la première image comprend l'application d'un procédé de réglage de niveau, et l'analyse de la seconde image comprend l'application d'une opération morphologique en niveaux de gris. Dans un autre mode de réalisation de l'invention, un algorithme d'étiquetage de composantes connexes peut être appliqué sur l'une quelconque des première et seconde images. L'invention porte en outre sur un système, un produit programme d'ordinateur et l'utilisation d'un procédé correspondant.
