Abstract
An x-ray sensorincludes a phosphorescent phosphorsusceptible to x-ray irradiationfor forming an image in the phosphor, the phosphor having a decay periodpersistent after an irradiation period. A photoelectric sensor arrayis arranged to receive phosphorescent emission from the phosphorescent phosphorcorresponding to the image. The photoelectric sensor array is gated off for a gated periodduring at least some of, or exceeding, the irradiation periodto 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.
