Influence of beam hardening in dualenergy CT imaging: phantom study for iodine mapping, virtual monoenergetic imaging, and virtual non-contrast imaging

Influence of beam hardening in dualenergy CT imaging: phantom study for iodine mapping, virtual monoenergetic imaging, and virtual non-contrast imaging
In this study, we investigated the influence of beam hardening on the dual-energy computed tomography (DECT) values of iodine maps, virtual monoenergetic (VME) images, and virtual non-contrast (VNC) images. 320-row DECT imaging was performed by changing the x-ray tube energy for the first and second rotations.
