摘要：A filtering device includes an X-ray translucent substrate having a plurality ofsepta disposed therein at a plurality of fixed positions with respect to the substrate. A
controller is programmed to acquire a first set of projection data at a first energyspectrum by controlling the X-ray source to emit the X-rays at the first energy spectrumand controlling the position of the filtering device to focally align the plurality of septawith the X-ray beam emitted from the focal spot, and to acquire a second set of
projection data at a second energy spectrum with a mean energy greater than the meanenergy of the first energy spectrum by controlling the X-ray source to emit the X-rays atthe second energy spectrum and controlling a change in the position of the filteringdevice to focally misalign the plurality of septa with the X-ray beam emitted from thefocal spot.
