Radioterapi Linac Energi 6 MV Terhadap Kanker Serviks Pada Organ Rektum Menggunakan Teknik 3DCRT dan IMRT Di RSUP Sanglah Denpasar

Cervical cancer radiotherapy on the Linac aircraft uses a 6 MV energy photon beam with 3 Dimension Conformal Radiotherapy (3DCRT) and Intensity Modulation Radiation Therapy (IMRT) techniques. planning 3DCRT IMRT techniques is then compared by analyzing dose distribution or target volume (PTV) coverage through Conformity Index (CI) Homogeneity (HI) Organ At Risk (OAR) where risk organ that considered rectum. In this study, 30 data cervical patients were used at Installation Sanglah Hospital Denpasar plan using box system technique rotation angles of 00, 900, 1800, 2700 radiation 5000 cGy. Comparison these two done Dose Volume Histogram (DVH) curve PTV Treatment Planning System (TPS) computer. The results study indicate average CI value in 1.017542 while 1.019668, Mann Whitney test (Asymp.Sig = 0.492). Likewise, HI value, averaged 0.089494 was 0.093126 0.487), both values not significant. While percentage rectum irradiation are 96% 87%, respectively. can minimize absorbed OAR (rectum).
