PHOTON-COUNTING DETECTOR. |
摘要 |
An imaging system (100) includes a radiation source (110) with a focal spot (204) that emits a beam of x-ray photons that traverses an examination region (106). The imaging system further includes a photon counting detector array (122) that detects a sub-set of the x-ray photons that traverse an examination region. The imaging system further includes a controller (116) that generates and transmits a pause signal, in response to a calculated drop in an intensity of the emitted the beam of x-ray photons below a predetermined intensity level, which causes the photon counting detector array to pause detecting the sub-set of the x-ray photons. The imaging system further includes a counter (136) that counts, for each of a plurality of counting periods, the x-ray photons of the sub-set detected by the photon counting detector array in the corresponding counting period. |
