An x-ray inspection system ( 198 ) arranged to inspect at least one object and comprising: a source of radiation ( 200 ) a detector ( 216 ), in use, capable of detecting the radiation passing through an irradiation zone ( 214 ) and generating a periodic output of data therefrom; processing circuitry arranged to process the output generated by the detector ( 216 ); a speed determination means ( 228 ) arranged, in use, to determine and output to the processing circuitry the speed at which an object passes the detector ( 216 ); wherein the processing circuitry is arranged to vary the period of the output of the detector ( 216 ) according to the output from the speed determination means ( 228 ).
