Patent

CA 2339797

A method for the automated segmentation of an abnormality in a medical image, including acquiring first image data representative of the medical image; locating a suspicious site at which the abnormality may exist; establishing a seed point within the suspicious site; and preprocessing the suspicious site with a constraint function to produce second image data in which pixel values distant of the seed point are suppressed.

Ce procédé de segmentation automatique d'une anomalie dans une image médicale consiste à acquérir une première série de données d'image représentatives de l'image médicale, à localiser un site soupçonné d'abriter une anomalie, à établir un point-graine dans ce site suspect et à prétraiter ce site suspect à l'aide d'une fonction de contrainte pour produire une seconde série de données d'image dans laquelle les valeurs de pixel distantes du point-graine sont supprimées.
