Detectors for computed tomography scanners and related assemblies and systems

An assembly of detectors for a computed tomography scanner, comprising:

• an array of detectors, each detector of the array of detectors comprising:
• a cathode;
• a detector material capable of converting each photon received at the detector material into an electrical signal to perform photon counting computed tomography, the detector material in contact with the cathode;
• and
• an array of anodes located on a side of the detector material opposite the cathode;
• a first substrate facing the array of anodes, anodes of the array of anodes electrically connected to the substrate;
• and
• a microelectronic device located on a side of the substrate opposite the detector material, the microelectronic device electrically connected to the substrate with the microelectronic device mounted to the substrate in a flip-chip orientation;
• and
• a carrier supporting the array of detectors, the carrier comprising:
• a second substrate electrically connected to each first substrate of the array of detectors by electrically conductive elements located laterally adjacent to the microelectronic device and in contact with respective first substrates and the second substrate;
• and
• a connector located on a side of the second substrate opposite the array of detectors, the connector electrically connected to the electrically conductive elements.
