Abstract
A photon-counting detector includes a direct conversion material and a data acquisition system with a first comparator having a first signal level threshold indicative of a noise level of a spectrum of photons, the first comparator configured to output a count when the electrical signal level exceeds the first signal level threshold, and a second comparator having a second signal level threshold indicative of the maximum energy of the spectrum of photons, the second comparator configured to output a count when the electrical signal exceeds the second signal level threshold where a photon count is determined based on the counts from the first and second comparators.
