Abstract

La présente invention concerne, selon un mode de réalisation, un procédé de commande de dispositif thérapeutique destiné à commander un dispositif thérapeutique qui émet un rayonnement au niveau d'un patient, comprenant les étapes consistant : à acquérir, à des intervalles de temps réguliers, un signal d'image d'entrée, qui comprend des informations concernant la posture d'un patient et le contexte environnant et qui est composé d'une pluralité de pixels ; à convertir numériquement le signal d'image d'entrée de façon à générer des données d'image d'entrée comprenant des informations sur l'intensité de contraste de chacun de la pluralité de pixels ; à analyser si le changement dans les données d'image d'entrée dépasse une valeur seuil de changement prédéfinie de façon à générer des données d'image de référence ; à générer des données de mouvement, comprenant un vrai pixel ayant un mouvement et un faux pixel n'ayant pas de mouvement, selon que la différence entre les données d'image d'entrée les plus récemment générées et les données d'image de référence dépasse une valeur seuil de mouvement prédéfinie ; et à commander l'émittance de rayonnement du dispositif thérapeutique selon que la proportion des vrais pixels dans la pluralité de pixels dépasse une valeur seuil de commande prédéfinie sur la base des données de mouvement.
