Table 2.

Results of %NRMSE computation for the decomposition between cobalt-chromium, platinum, and iodine. All three of the materials were decomposed so that the %NRMSE is below the 10% threshold. The cobalt-chromium was the least accurate decomposition due to the shape of the struts being impacted by the reconstruction artifacts, as well as the error present in the CoCr mapping of the decomposition. The addition of the iodine reduced the accuracy of the platinum and CoCr decomposition.

NRMSE (%)
Co-Cr 8.9
Platinum 1.04
Iodine 3.6
