Title
(EN) ATTENUATION CHARACTERISTICS FOR OBJECTS
(FR) CARACTÉRISTIQUES D'ATTÉNUATION POUR DES OBJETS
Abstract
(EN) In an example, a method includes receiving an image indicative of attenuation of radiation by a first object. The method may include deriving object model data for use in generating a second object representing the first object in a radiation environment, using additive manufacturing. In some examples deriving the object model data includes deriving, from the image, a plurality of zones, each associated with a different radiation attenuation level, determining a radiation condition of the radiation environment, selecting, for each zone and based on the radiation condition, an additive manufacturing attribute comprising an additive manufacturing material and/or a material density for each zone, wherein the additive manufacturing attributes are associated with attenuation characteristics and deriving the object model data by combining selected additive manufacturing attributes to specify a plurality of regions of the second object, which, when the second object is generated, correspond to a geometrical configuration of the zones.
(FR) Dans un exemple, l'invention concerne un procédé consistant à recevoir une image indiquant une atténuation de rayonnement par un premier objet. Le procédé selon l'invention peut consister à obtenir des données de modèle d'objet servant à générer un deuxième objet représentant le premier objet dans un environnement de rayonnement, par fabrication additive. Dans certains exemples, l'obtention des données de modèle d'objet consiste : à obtenir, à partir de l'image, une pluralité de zones, chacune étant associée à un niveau d'atténuation de rayonnement différent ; à déterminer une condition de rayonnement de l'environnement de rayonnement ; à sélectionner, pour chaque zone et en fonction de la condition de rayonnement, un attribut de fabrication additive comprenant un matériau de fabrication additive et/ou une densité de matériau pour chaque zone, les attributs de fabrication additive étant associés à des caractéristiques d'atténuation ; et à obtenir les données de modèle d'objet par combinaison d'attributs de fabrication additive sélectionnés pour définir une pluralité de zones du deuxième objet qui, lorsque ce dernier est généré, correspondent à une configuration géométrique des zones.
