Abstract

A limitation of the use of multiple scanning beams for scatter reduction in radiography is the possible creation of artifactual aperture patterns which can be caused: (1) by a synchronization between the pattern scanning frequency and the radiation waveform ripple frequency, or (2) by the fractional overlap of the scanning beams during the final beam pass. An analysis of the stages of artifact formation and the implications for various scanning beam approaches is presented.
