Abstract

According to the present invention, an X-ray readout integrated circuit comprises: an amplification unit that converts a charge quantity, which was generated from a photodiode when X-rays were incident, into a voltage output signal and outputs the converted signal; comparator unit that compares the voltage output signal with an N preset reference voltage, respectively, and outputs the voltage output signal as an N comparative output signal; a band determination unit that activates a pulse output signal, if the comparative output signals satisfy a determined condition which is set to detect an X-ray of a specific energy band; and a counter unit that counts the number of pulses of the pulse output signal, and outputs photon counting data.
