Abstract
The present invention teaches a new and unique method and apparatus of resolving the inaccuracy related to high photon counting rate in photon counting-based detectors that comprises a sensor, a discriminator and a counter. According to the method, a circuitry is provided at the output of the discriminator wherein the circuitry is adapted to measure duty cycle of a signal by which an indication of an input rate of photons to the discriminator is established.
