In the article titled, “Clinical implications of Eclipse analytical anisotropic algorithm and Acuros XB algorithm for the treatment of lung cancer” published in pages 219-223, issue 4, vol. 41 of Journal of Medical Physics,[1] the fifth and sixth sentences under the section “Introduction” are written incorrectly as ’Type “A” was proposed by Knöös et al.[3] which were based on measurements and accounts for correction for patient contours and heterogeneities. Type “B” was proposed by Ojala et al.[4] which were based on superposition and convolution techniques.’ instead of ’Type “A” and “B” were proposed by Knöös et al.[3] Type “A” was based on measurements and accounts for correction for patient contours and heterogeneities. Type “B” was based on superposition and convolution techniques. Ojala et al.[4] proposed type “C ”.’
