1. A radiation detection apparatus, comprising:

  • a radiation detector which generates an electrical signal by interacting with X-rays;

    an Analog-to-Digital Converter (ADC) which is coupled to the radiation detector and converts the electrical signal to a waveform data;

    a data processor which determines the number of single photon signals according to the waveform data from the ADC, and determines whether an integral signal and/or a count signal of the waveform data will be used for imaging according to the number of the single photon signals, comprising;

    using the integral signal of the waveform data as an imaging signal to perform imaging if the number of the single photon signals is less than a predetermined lower threshold, and using the count signal of the waveform data as an imaging signal to perform imaging if the number of the single photon signals is greater than a predetermined upper threshold; and

    an imaging apparatus which;

    performs imaging according to the integral signal of the waveform data when the number of the single photon signals is less than thepredetermined lower threshold; and

    performs imaging according to the count signal of the waveform data when the number of the single photon signals is greater than thepredetermined upper threshold.
