Local storage device in high flux semiconductor radiation detectors and methods of operating thereof

A detector element circuit in a CT imaging system, comprising:

• a plurality of radiation sensors for detecting photons attenuated by an object;
• a first electronic component configured to determine an energy of photons detected by the plurality of radiation sensors and generate digitized photon count data, wherein the digitized photon count data comprises a digitized count of detected photons in one or more energy bins;
• a field programmable gate array (FPGA) configured to receive the digitized photon count data from the first electronic component and generate an output representing the digitized photon count data, wherein the FPGA comprises a FPGA clock configured to control a rate at which the FPGA receives the digitized photon count data from channels of the first electronic component and at which the FPGA outputs the output representing the digitized photon count data;
• and
• a local memory storage configured to receive the output representing the digitized photon count data from the FPGA and comprising a local storage clock configured to control a rate at which the local memory storage generates buffered output data derived from the digitized photon count data,
• wherein:
• the FPGA clock and the local storage clock are set such that the FPGA is clocked at a first clock rate and the local storage element outputs the buffered output data at a second clock rate;
• and
• the second clock rate and the first clock rate are selected to reduce bottlenecks or data transfer issues imposed by bandwidth limitations between the local memory storage and a computer of the CT imaging system that is configured to receive the buffered output data from the local memory storage.
