A CdZnTe photon counting detector includes a core material of CdZnTe, where (0&#x2266;x&#x3c;1), an anode terminal on one side of the core material and a cathode terminal on a side of the core material opposite the anode terminal. At least one of the following is selected in the design of the detector as a function of the maximum sustainable photon flux the core material is able to absorb in operation while avoiding polarization of the core material: electron lifetime-mobility product of the core material; de-trapping time of the core material; a value of a DC bias voltage applied between the anode and the cathode; a temperature of the core material in operation; a mean photon flux density to be absorbed by the core material in operation; and a thickness of the core material between the anode and the cathode.

CdZnTe device using constrained design for high-flux x-ray spectroscopic imaging applications

In operation of a photon counting detecting system (), a number of pulse counts output by least one pixel () of a photon counting detector in response to experiencing a photon flux density during a sample interval is acquired and a photon flux density () or value related thereto corresponding to the pulse counts output by the pixel () is determined. A correction () for the thus determined photon flux density () or value related thereto is determined. A corrected number of pulse counts () is determined for the pixel () as a function of the thus determined corrected photon flux density value or value related thereto. An image can be displayed that is a function of the corrected number of pulse counts for pixels of the system.
