One embodiment is a method for counting charge events detected by a pixel in a photon-counting computed tomography (PCCT) scanning system comprising a plurality of discriminators, wherein each discriminator is associated with a respective one of a plurality of threshold voltage levels. The method includes detecting a signal output from one of the discriminators; incrementing a quantitative count corresponding to the threshold voltage level associated with the one of the discriminators if the detected discriminator output signal meets a first condition; and incrementing a qualitative count if the detected discriminator output signal meets at least one second condition.
