In the article titled “Polychromatic Iterative Statistical Material Image Reconstruction for Photon-Counting Computed Tomography” [1], there were errors in equations (13) and (28) in addition to some errors in the text. This should be corrected as follows:

Equation should be corrected to

The text between equations and should be corrected to

Since is a convex function, it holds that

(3) Equation (28) should be corrected to

In the “Summary of the Algorithm” subsection, step 3 should be corrected to

Additionally, calculate

which equates to .
