Abstract

Radiotherapy helps kill cancer cells in patients. In the radiotherapy process, radiation quality assurance is needed to maintain consistency and safety in administering doses to the target. The implementation of radiotherapy in patients requires planning made by medical physicists. In this study, radiotherapy treatment planning was carried out using the 3D Slicer-SlicerRT in the case of lung cancer with the diagnosis of stage II squamous cell carcinoma, male sex and consisted of 1 nodule. Patient data is obtained from The Cancer Imaging Archive, NSCLC-Radiomics. The method in this study began with processing patient data with a total fraction recipe of 60 Gy/30 and 63 Gy/30. The variations given are combination gantry angles of 0°,45°,90°,135°,180°, and 225°, with the number of beams being 4, 5, and 6. Furthermore, the value of the homogeneity index, tissue density, and electron density was evaluated. Dosage planning is limited to 95-107% of the dosage determined based on the ICRU 50. This study obtained the results of tissue density and electron density relatively by the reference standards for each organ. The treatment planning results are by the total standard and have the best homogeneity index of 0.25449 for five beams.
