Title (EN) GRID FOR SELECTIVE TRANSMISSION OF X-RAY RADIATION, AND METHOD OF MANUFACTURING SUCH A GRID
(FR) GRILLE POUR LA TRANSMISSION SÉLECTIVE D’UN RAYONNEMENT DE RAYONS X, ET PROCÉDÉ DE FABRICATION DE LA GRILLE
Abstract:
(EN) A grid (1) for selective transmission of electromagnetic radiation and a method for manufacturing such grid is proposed. Therein, the grid (1) for selective transmission of electromagnetic radiation comprises a structural element (2) comprising a plurality of particles (19) comprising a radiation-absorbing material. The particles (19) are sintered together such that pores (21) are present between neighbouring particles (19). The pores (21) are at least partially filled with a polymer. The polymer increases the mechanical stability of the grid and improves the handling properties.
(FR) L’invention concerne une grille (1) pour la transmission sélective d’un rayonnement électromagnétique et un procédé de fabrication de la grille. L’intérieur de la grille (1) pour la transmission sélective d’un rayonnement électromagnétique comprend un élément structurel (2) comprenant une pluralité de particules (19) comprenant un matériau absorbant les rayonnements. Les particules (19) sont réunies par un frittage conduisant à la présence de pores (21) entre particules voisines (19). Les pores (21) sont remplies au moins partiellement d’un polymère. Le polymère augmente la stabilité mécanique de la grille et améliore les propriétés de manipulation.
