In this work, organized as a short review, we present some results obtained by applying the Monte Carlo techniques in the Intra-Operative Radiation Therapy (IORT). The electron beams generated by the NOVAC7 IORT accelerator have been simulated using BEAMnrc/EGSnrc Monte Carlo code, the dose distributions and water-to-air stopping power ratios being later calculated with the associated software ...

The GATE 6.1 Monte Carlo simulation platform based on the GEANT4 toolkit is in constant 15 improvement for dosimetric calculations. Here, we explore its use for calculating internal absorbed dose distribution in mice for the treatment of malignant melanoma after injection of a new specific radiopharmaceutical labeled with iodine 131. We estimate the dosimetric accuracy of GATE 6.1, by calculati...

Nghiên cứu này áp dụng phương pháp mô phỏng Monte Carlo Mã EGSnrc với hai mã là chuyên dụng, BEAMnrc được sử để chùm tia phát ra từ đầu máy gia tốc và DOSXYZnrc tính toán liều lượng tốc. Từ đó, đánh giá sự suy giảm của bức xạ qua các lớp vật liệu che chắn. Kết quả nghiên ban cho thấy giới hạn ở khu vực nhân viên (khu Kiểm soát) 0,11 mSv / tuần (5,5 năm) công cộng Không kiểm 0,022 (1,1 ).

The purpose of this study is to validate Eclipse's electron Monte Carlo algorithm (eMC) in heterogeneous phantoms using radiochromic films and EGSnrc as a reference Monte Carlo algorithm. Four heterogeneous phantoms are used in this study. Radiochromic films are inserted in these phantoms, including in heterogeneous media, and the measured relative dose distributions are compared to eMC calcula...

PURPOSE The purpose of this study is to obtain the dosimetric parameters of the new BEBIG (60)Co brachytherapy source following by TG-43U1 recommendation with appropriate electron cutoff energy (0.521 MeV). MATERIAL AND METHODS The new BEBIG (60)Co brachytherapy source is used to calculate the TG-43U1 parameters. EGSnrc-based Monte Carlo simulation code has been used to calculate the radial d...
