Abstract

The purpose of the study was to investigate the physical properties of the EBT2 radiochromic films and define the conditions of its clinical applicability. We irradiated the films with different treatment techniques 3D conformal (3DCRT), intensity-modulated (IMRT) and stereotactic body radiotherapy with arc therapy (SBRT), and then compared the data with the dose distribution exported from the treatment planning system (Eclipse). Two film analysis softwares were investigated for the comparison: PTW Mephysto and FilmQA Pro. The comparisons of dose distributions were performed with gamma analysis, and the gamma criterion was 3%, 3mm, and 2%, 2mm. The gamma analysis results by the two programs were the following, (PTW/FilmQA Pro) with 3%, 3mm gamma criterion: 3DCRT (95,5/100%), IMRT (97/99,9%), SBRT (99,7/100%). In case of 2%, 2mm the results were: 3DCRT (87,1/98,9%), IMRT (92/98,5%), SBRT (96,7/97,9%). Based on the results it can be stated that during proper use, the features of the scanner do not affect the results. Both evaluation softwares are suitable for calibrating and evaluating films, moreover, performing the gamma analysis. The EBT2 film is suitable for the two-dimensional controlling of radiation therapy plans.
