Photon-counting detector with count-rate dependent multiplexing

A method for a photon-counting apparatus, comprising:

• generating a plurality of photon-counting signals based on impingement of photons on a plurality of photon-counting detectors;
• converting at least a subset of the plurality of photon-counting signals to digital photon-counting signals in a plurality of analog-to-digital conversion circuits;
• determining a photon-count rate in a processor;
• and
• causing an intelligent multiplexer to modify interconnections between the plurality of photon-counting detectors and the plurality of analog-to-digital conversion circuits based on the photon-count rate, the intelligent multiplexer providing a selected set of digital photon-counting signals to the processor.

A non-transitory computer-readable medium encoded with computer-readable instructions thereon that, when executed by a computer, cause the computer to perform a method comprising:

• generating a plurality of photon-counting signals based on impingement of photons on a plurality of photon-counting detectors;
• converting at least a subset of the plurality of photon-counting signals to digital photon-counting signals in a plurality of analog-to-digital conversion circuits;
• determining a photon-count rate in a processor;
• and
• causing an intelligent multiplexer to modify interconnections between the plurality of photon-counting detectors and the plurality of analog-to-digital conversion circuits based on the photon-count rate, the intelligent multiplexer providing a selected set of digital photon-counting signals to the processor.
