Abstract

L'invention concerne un dispositif permettant l'acquisition des coordonnées d'au moins un point d'un objet à partir d'images de télévision et la synthèse d'un point image à partir de ces coordonnées. Ce dispositif comprend les moyens 50 décrits dans la demande de brevet principale, complétés par un sélecteur à commande manuelle 51, une mémoire de stockage 52, une mémoire tampon 53, le cas échéant des moyens de visualisation des coordonnées 54, un synthétiseur 55, 56, 57 pour chaque point à synthétiser et un mélangeur à fonction logique OU 58 pour fournir des impulsions au mélangeur VIDEO du dispositif de base 50 et engendrer en surimpression sur l'écran du moniteur des zones lumineuses de petites dimensions correspondant aux points synthétisés. Ce dispositif permet de réaliser un positionnement reproductible d'un objet ou d'un corps dans l'espace et peut en particulier s'appliquer dans le domaine médical des traitements par rayons.
