ABSTRACT:
An x-ray sensor60includes a phosphorescent phosphor601susceptible to x-ray irradiation12for forming an image in the phosphor, the phosphor having a decay period71persistent after an irradiation period75. A photoelectric sensor array603is arranged to receive phosphorescent emission from the phosphorescent phosphor601corresponding to the image. The photoelectric sensor array is gated off for a gated period72during at least some of, or exceeding, the irradiation period75to dump output from the photoelectric sensor array means generated during at least some of the irradiation period to reduce the effect of direct x-ray irradiation of the photoelectric sensor array. A signal is at least primarily output from the sensor from persisting phosphorescence from the phosphor during the decay period.
