Scintillating glass pixelated imager

Abstract:

In a method of making pixelated scintillators, a block of an amorphous scintillator material is divided into plural sections. The plural sections of the block are rejoined with plural first reflective septa to form an assembly. In the assembly, each of the plural first reflective septa separates two adjacent sections of the block. The assembly is then divided into plural sections in a way such that each of the plural sections of the block is divided into plural pixels. The plural sections of the assembly are rejoined with plural second reflective septa. Each of the plural second reflective septa separates two adjacent sections of the assembly, forming an array comprising plural rows and columns of pixels of the amorphous scintillator material. In the array, each pixel is separated from adjacent pixels by a portion of at least one of the plural first reflective septa and at least one of the second reflective septa.
