Dosimetric evaluation in carcinoma lung by intraluminal brachytherapy and correlation in phantom model

Abstract

In the carcinoma lung patient, endobronchial brachytherapy (EBBT) is used as treatment modality. The radiation dose to the tumor is planned in the treatment planning system (TPS) on the CT scan of the patient and treatment delivered by the machine. Treatment plan verification, dosimetric, volumetric analysis is necessary to perform for accurate treatment delivery to the patient, which requires a tissue equivalent phantom model mimicking the actual thoracic body structure because in the actual patient, dosimetry is not possible. In this study, the dosimetric analysis is performed in the locally fabricated human tissue equivalent thorax phantom with the help of Radiochromic film dosimeters. Dosimetric and volumetric analysis is performed on patients treated with EBBT technique.
