Dynamic bowtie in fan-beam geometry for a balanced flux distribution upon an equiangular detector array.

Abstract

<p>(a) No object in the field of view (FOV) corresponds to a liquid highly attenuating bowtie (HB); (b) an elliptical phantom in the FOV corresponds to the HB containing a weakly attenuating bowtie (WB) that compensates for the attenuation due to the phantom; and (c) the WB is synchronously rotated with the gantry for dynamic compensation (for example, ).</p
