Abstract
(EN) A computer-implemented method is provided for improving live video quality. The method comprises: acquiring, using a medical imaging apparatus, a stream of consecutive image frames of a subject, and the stream of consecutive image frames are acquired with reduced amount of radiation dose; applying a deep learning network model to the stream of consecutive image frames to generate an image frame with improved quality; and displaying the image frame with improved quality in real-time on a display.
(FR) L'invention concerne un procédé mis en œuvre par ordinateur permettant d'améliorer la qualité vidéo en direct. Le procédé consiste : à acquérir, à l'aide d'un appareil d'imagerie médicale, un flux de trames d'image consécutives d'un sujet, et le flux de trames d'image consécutives est acquis à l'aide d'une quantité réduite de dose de rayonnement ; à appliquer un modèle de réseau d'apprentissage profond au flux de trames d'image consécutives afin de générer une trame d'image ayant une qualité améliorée ; et à afficher la trame d'image à l'aide d'une qualité améliorée en temps réel sur un dispositif d'affichage.
