Dosimetric Verification Using Monte Carlo Calculations for Tissue Heterogeneity-corrected Conformal Treatment Plans Following RTOG 0813 Dosimetric Criteria for Lung Cancer Stereotactic Body Radiotherapy

摘要

PurposeThe recently activated RTOG studies on stereotactic body radiation therapy (SBRT) of non-small cell lung cancer (NSCLC) require tissue density heterogeneity correction, where the high and intermediate dose compliance criteria were established based on superposition-algorithm dose calculations. The study was aimed to compare superposition-algorithm dose calculations with Monte Carlo (MC) dose calculations for SBRT NSCLC treatment and to evaluate whether compliance criteria need to be adjusted for MC dose calculations.
