The z‐sbDBA, a new concept for a dynamic sheet‐based fluence field modulator in x‐ray CT

Purpose We present a new concept for dynamic fluence field modulation (FFM) in x‐ray computed tomography (CT). The so‐called z‐aligned sheet‐based dynamic beam attenuator (z‐sbDBA) is developed to dynamically compensate variations in patient attenuation across the fan beam and the projection angle....
