Title (EN) SYSTEMS AND METHODS FOR ANALYSIS OF TISSUE IMAGES
(FR) SYSTÈMES ET PROCÉDÉS D’ANALYSE D’IMAGES DE TISSU
Abstract:
(EN) There is provided a method of computing at least one slide-level tissue type for a tissue image of tissue extracted from a patient, comprising: receiving a tissue image of a slide including tissue extracted from the patient, segmenting tissue objects of the tissue image, creating a tissue image patches from the segmented tissue objects of the tissue image, classifying, by a patch-level classifier, each of the plurality of tissue image patches into at least one patch-level tissue type, wherein each of the classified tissue image patches is associated with a relative location within the tissue image, analyzing, by a slide-level analysis code, the classified at least one patch-level tissue type and associated relative location for each of the plurality of tissue image patches outputted by the patch-level classifier, for computing at least one slide-level tissue type for the tissue image, and providing the at least one slide-level tissue type.
(FR) L'invention concerne un procédé de calcul d'au moins un type de tissu sur lame pour une image de tissu d'un tissu extrait d'un patient, comprenant : la réception d'une image de tissu d'une lame comprenant un tissu extrait du patient, la segmentation d'objets de tissu de l'image de tissu, la création de patches d'images de tissu à partir des objets de tissu segmentés de l'image de tissu, la classification, par un classificateur de niveau de patch, de chacune de la pluralité de patches d'images de tissu en au moins un type de tissu de niveau de patch, chacun des patches d'images de tissu classés étant associé à un emplacement relatif à l'intérieur de l'image de tissu, l'analyse, au moyen d'un code d'analyse sur lame, du ou des types de tissu de niveau de patch classés et de l'emplacement relatif associé pour chacun de la pluralité de patches d'images de tissu délivrés en sortie par le classificateur de niveau de patch, pour calculer au moins un type de tissu sur lame pour l'image de tissu, et la fourniture du ou des types de tissu sur lame.
