Abstract

La présente invention concerne, selon un mode de réalisation, un dispositif de fabrication d'un ensemble de blindage contre le rayonnement comprenant : une unité de stockage dans laquelle des données de plan de traitement générées par un système de radiothérapie externe sont stockées; une unité de traitement pour la réception des données de plan de traitement transmises depuis l'unité de stockage et pour la génération d'informations relatives à un ensemble de blindage visant à assurer une protection contre un rayonnement émis par une unité source de lumière du système de radiothérapie; et une unité de sortie pour la réception des informations relatives à l'ensemble de blindage transférées depuis l'unité de traitement et pour la production de l'ensemble de blindage selon une forme tridimensionnelle, l'ensemble de blindage comportant une partie pénétrante dont la forme correspond à une zone d'irradiation qui reçoit le rayonnement pendant une radiothérapie.
