A computed tomography (CT) detector apparatus includes a plurality of detectors arranged in a ring, each detector being arranged inside a Faraday cage having a plurality of voltage-biased side-electrodes arranged on a side surface of the Faraday cage. The detectors include photon-counting detectors (PCDs). A voltage applied to the voltage-biased side-electrodes decreases from the anode side of the PCD to the cathode side of the PCD.

A shock detection device for a detector array includes an accelerometer mounted on the detector array to detect vibrations. The shock detection device also includes an electronic memory to store data from the accelerometer. The data corresponds to detected vibrations that exceed an active threshold of the accelerometer. The shock detection device also includes a power supply that is separate from the power supply of the detector array.

A control circuit for a computer-aided tomography (CT) system includes an input that receives a master timing signal and an input that receives a first timing signal. The control circuit includes a mode detection circuit that determines the scan mode of the CT system based on the master timing signal and a first timing signal, where the frequency of the first time signal is lower than the frequency of the master timing signal. The control circuit also includes a circuit that generates a second timing signal based on the master timing signal and the scan mode, where the second timing signal that has a lower frequency than the master timing frequency but a higher frequency than the frequency of the first timing signal.
