SPECTRAL PHOTON COUNTING DETECTOR |
摘要 |
An apparatus includes a scale factor determiner (236) that determines a count scale factor based on a measured count of a number detected photons for an energy threshold and an estimated actual count of the number of detected photons. The photons include poly-energetic photons detected by a radiation sensitive detector. The apparatus further includes a count sealer (136) that employs the count scale factor to scale measured counts of detected photons for different energy thresholds.
