SPECTRAL COMPUTED TOMOGRAPHY USING CORRELATED PHOTON NUMBER AND ENERGY MEASUREMENTS |
摘要 |
A computed tomography system includes a plurality of radiation sensitive detector elements (100) which generate a time varying signals indicative of x-ray photons received by the various detector elements (100). Photon counters (24) count the photons received by the various detector elements (24). Event-driven energy determiners (26) measure the total energy of the received photons. A mean energy calculator (46) calculates a mean energy of the photons received by the various detector elements (100) during a plurality of reading periods. |
