ASSESSMENT OF TREATMENT PLAN QUALITY BETWEEN FLATTENING FILTER AND FLATTENING FILTER FREE PHOTON BEAM FOR CARCINOMA OF THE ESOPHAGUS WITH IMRT TECHNIQUE

Assessment of Treatment Plan Quality between Flattening Filter and Flattening Filter Free Photon Beam for Carcinoma of the Esophagus with IMRT Technique

Background: As compared to the flattened photon beam, removing the flattening filter (FF) from the head of a gantry decreases the average energy of the photon beam and increases the dose rate, leading to an impact on the quality of treatment plans.Objective: This study aimed to compare the quality of intensity-modulated radiation therapy (IMRT) tre
