Treatment planning for lung cancer is challenging , especially in the case of treatment plan involving small fields . The combination of low - density (air) medium and small fields cause charge particle disequilibrium nears the air / tissue interface . Beam modeling within the dose calculation algorithms must also employ an accurate method of accounting tissue heterogeneity corrections in order to avoid dose overestimation or underestimation . Analytical anisotropic algorithm (AAA) is one of the widely tested and validated dose calculation algorithms in external beam photon radiation ther - apy . Recently , Acuros XB (AXB) was made available for photon dose calculations , and several studies have demonstrated better dose prediction accuracy of the AXB over AAA . This article reviews the results from the treatment planning studies , which have investigated the clinical dosimetric impact of the AXB and AAA on real lung cancer treatment plans .
