Abstract :The aim of this study was to investigate the effect of the use of intermediate dose calculation module on dose volume histogram insert ignore into journalissuearticles values(DVH); during dose optimization in the treatment plans of radiotherapy patients diagnosed with lung cancer. This study was carried out by using Eclipse insert ignore into journalissuearticles values(Version 15.3); treatment planning system with Trilogy model Linear Accelerator device in Radiation Oncology Department of Şişli Hamidiye Etfal Training and Research Hospital. Ten patients with lung cancer were included in the study. In this study, critical organ doses, conformity index insert ignore into journalissuearticles values(CI); and homogenity index insert ignore into journalissuearticles values(HI); were compared by making optimization in cases where intermediate dose calculation module was active and inactive. The plans using the Intermediate dose calculation model are more homogeneous and uniform. Differences between critical organ doses, conformity index insert ignore into journalissuearticles values(CI); and homogenity index insert ignore into journalissuearticles values(HI); were statistically significant when using the Intermediate dose calculation module. It has been demonstrated that the intermediate dose calculation method in heterogeneous lung cancer patients is superior in terms of dose homogeneity and tumor volume enveloping, which improves the quality of treatment plans.
