Abstract
A previously proposed method for beam hardening correction is illustrated using a mathematically described phantom based on an actual reconstructed cross-section of a human head. The method consists of a combination of polynomial correction of the polyenergetic data and an iterative estimation of the monoenergetic data based on previous reconstructions The quality of reconstructions is found to be similar to those which can be obtained from monoenergetic data.
