Abstract: Among other things, an anti-scatter collimator is provided including a first layer defining a first retaining member at a first surface. A second layer defines a second retaining member at a first surface that faces the first surface of the first layer. A septum is disposed between the first layer and the second layer and physically contacts the first retaining member and the second retaining member. The first retaining member and the second retaining member maintain a position of the septum relative to the first layer and the second layer. The septum has a third attenuation coefficient that is greater than a first attenuation coefficient of the first layer and a second attenuation coefficient of the second layer. An end support is attached to the first layer and to the second layer. The end support borders an end of the septum.

Abstract: A detector array is provided for detecting radiation photons. The detector array includes a phosphor screen that converts radiation photons into light energy. The detector array includes a photodiode array having a plurality of photodiodes that convert the light energy into electrical charge. A first photodiode of the plurality of photodiodes is spaced apart from a second photodiode of the plurality of photodiodes to define a non-detection region. The phosphor screen overlies the first photodiode, the second photodiode, and the non-detection region between the first photodiode and the second photodiode.

Abstract: Among other things, a detector array (300) for a radiation imaging system is provided. The detector array comprises a plurality of detector elements. Respective detector elements comprise, among other things, a scintillator (304) and a photodetector (306). In some embodiments, a scintillator is shared amongst two or more of the detector elements. In some embodiments, little to no reflective material, configured to mitigate cross-talk between detector elements, is situated between two or more detector elements.
