Patent

CA 2731642

A computer-based method of determining a functional assessment of at least one organ having secretional or excretional functions, such as a liver or kidneys, of a human is disclosed. The method comprises processing a four- dimensional (4D) image data set of said human comprising data for an assessment of said organ function, wherein said 4D image data is acquired by an image modality; and wherein said processing said 4D image data comprises performing a deconvolutional analysis (DA) comprising a matrix inversion using singular value decomposition (SVD) based on said 4D image data.

La présente invention concerne un procédé assisté par ordinateur de détermination dune évaluation fonctionnelle dau moins un organe ayant des fonctions de sécrétion et dexcrétion, tel que le foie ou les reins, dun humain. Le procédé comprend le traitement dun ensemble de données dimage en quatre dimensions dudit humain comprenant des données pour une évaluation de la fonction dudit organe, les données dimage en quatre dimensions étant acquises par une modalité dimagerie ; ledit traitement desdites données dimage en quatre dimensions comprend la réalisation dune analyse par déconvolution (DA) comprenant une inversion des matrices à laide dune décomposition en valeurs singulières (SVD) basée sur lesdites données dimage en quatre dimensions.
