Abstract: Detectors for computed tomography scanners may include a cathode, a cadmium telluride material, a cadmium zinc telluride material, or a silicon material adjacent to the cathode, and an array of anodes located on a side of the cadmium telluride material, the cadmium zinc telluride material, or the silicon material opposite the cathode, A substrate may be located proximate to the array of anodes, anodes of the array of anodes electrically connected to the substrate. A microelectronic device may be located on a side of the substrate opposite the cadmium telluride material, the cadmium zinc telluride material or the silicon material. The microelectronic device may be electrically connected to the substrate with the microelectronic device mounted to the substrate in a flip-chip orientation. Electrically conductive elements may be located adjacent to the microelectronic device and electrically connected to the substrate.
