Abstract

L'invention concerne des systèmes et des procédés qui permettent une détection et une caractérisation améliorées de lésions chez un sujet par analyse automatisée d'images médicales nucléaires, telles que des images de tomographie par émission de positrons (TEP) et de tomographie par émission de simples photons (TESP). En particulier, dans certains modes de réalisation, les approches décrites dans la description tirent profit de l'intelligence artificielle (IA) pour détecter des régions d'images médicales nucléaires 3D correspondant à des points chauds qui représentent des lésions cancéreuses potentielles chez le sujet. Les modules d'apprentissage automatique peuvent être utilisés non seulement pour détecter la présence et les emplacements de telles régions dans une image, mais également pour segmenter la région correspondant à la lésion et/ou pour classifier de tels points chauds sur la base de la probabilité pour qu'ils indiquent une véritable lésion cancéreuse sous-jacente. Lesdites détection, segmentation et classification de lésion basées sur l'IA peuvent fournir une base pour une caractérisation supplémentaire de lésions, une charge tumorale globale et une estimation de la gravité et du risque de maladie.
