Dynamic Iterative Beam Hardening Correction (DIBHC) in Myocardial Perfusion Imaging Using Contrast-Enhanced Computed Tomography

In cardiac perfusion examinations with computed tomography (CT) large concentrations of iodine in the ventricle and in the descending aorta cause beam hardening artifacts that can lead to incorrect perfusion parameters. The aim of this study is to reduce these artifacts by performing an iterative correction and by accounting for the 3 materials soft tissue, bone, and iodine.Beam hardening corrections are either implemented as simple...
