Methods for fabricating pixelated scintillator arrays

Abstract

A method of making pixelated scintillator arrays employs a first jig comprising a plurality of recesses and a second jig comprising a plurality of recesses. A plurality of or N scintillator pixels are placed in a plurality of or N recesses of the first jig. The N scintillator pixels have a shape such that a portion of each of the N scintillator pixels is conformably received in one of the N recesses of the first jig, e.g. a portion of each of the N scintillator pixels is received in and conforms to the shape of one of the N recesses. The remaining portion of each of the N scintillator pixels protrudes out from the recess, forming N protrusions substantially conforming to the shape of the recesses of the second jig. An adhesive layer is applied on the N protrusions of the N scintillator pixels. A reflective layer is placed over the N protrusions of the N scintillator pixels. The recesses of the second jig are aligned with the N protrusions of the N scintillator pixels and the reflective layer is pressed with the second jig such that at least a portion of the reflective layer conforms to the N protrusions of the N scintillator pixels, forming a first row of a scintillator array comprising the N scintillator pixels and the at least portion of the reflective layer.
