A detecting apparatus includes a multi-tier 3D integrated ASIC comprising one or more analog tiers and one or more digital tiers, and a sensor bonded to the multi-tier 3D integrated ASIC. The detecting apparatus includes an electrical substrate and a group of FPGAs or custom data management ASICs. The detecting apparatus also includes a thermal management system, a power distribution system and one or more connectors to transfer data to a data acquisition system configured for radiation spectroscopy or imaging with zero suppressed or full frame readout.

Edgeless large area camera system

A radiation detectorhas a plurality of single-photon-counting imaging cells, including an imaging cellconfigured to generate a detection signal in accordance with the intensity of radiation, a digitization circuitconfigured to digitize the detection signal, a data read structureconfigured to count the digitized detection signal and to keep the result as a data bit, and a send-out registerconfigured to control the input of a predetermined data bit output from the data read structureby a data shift in accordance with a first clock Pck, to keep the input data bit as a result of the control, and to send out the kept data bit by a data shift in accordance with a second clock Sck.

Radiation detector

There is provided a radiation detector that appropriately corrects an offset within a minute read cell without increasing area while achieving high-speed measurement at a high counting rate. A radiation detectorhaving a plurality of single-photon-counting imaging cells includes, for each imaging cell, a photodiodewhich is applied with a reverse bias voltage and generates a current signal in response to incidence of radiation, a previous-stage DA converter dconfigured to correct an input signal based on the current signal generated by the photodiode, an amplifier kconfigured to amplify the signal corrected by the previous-stage DA converter d, a subsequent-stage DA converter dconfigured to correct a charge signal amplified by the amplifier k, a wave height discriminatorconfigured to discriminate output signals based on the signal corrected by the subsequent-stage DA converter d, and a counterconfigured to count the discriminated signals.
