This article [J. Med. Imag. 3(2), 023503 (2016)] was originally published online on 6 May 2016 with a copyeditor error in the abstract. The sentence “The data-model agreement expressed as weighted coefficient of variation (${\mathrm{COV}}_{\mathrm{W}}$) was better than ${\mathrm{COV}}_{\mathrm{W}}=20\%$ for dead time losses…” has been changed to read: “The data-model agreement expressed as weighted coefficient of variation (${\mathrm{COV}}_{\mathrm{W}}$) was better than ${\mathrm{COV}}_{\mathrm{W}}=2.0\%$ for dead time losses…” The ${\mathrm{COV}}_{\mathrm{W}}$ value was missing a decimal point.

This article was corrected online on 11 May 2016. It appears correctly in print.
