[This corrects the article DOI: 10.1155/2016/5871604.].

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:

(1) Equation (13) should be corrected to

(2) The text between equations (14) and (15) should be corrected to

Since h is a convex function, it holds that

(3) Equation (28) should be corrected to

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

(3) Additionally, calculate

which equates to .
