Abstract: A method for fabricating a pixelated scintillator including providing a pixelated scintillator-structure and a connection-structure in such a way that the connection-structure is in mechanical contact with two adjacent pixels of the pixelated scintillator-structure. Moreover, the pixelated scintillator-structure includes a first sintering-shrinking-coefficient and the connection-structure includes a second sintering-shrinking-coefficient that is greater than the first sintering-shrinking-coefficient. Further, the pixelated scintillator-structure and the connection-structure are sintered such that a gap between two adjacent pixels of the pixelated scintillator-structure is reduced.
