In brachytherapy (BT), or internal radiation therapy, cancer is treated by radioactive implants. For instance, episcleral plaques (EPs) for the treatment of uveal melanoma, are designed according to generic population approximations. However, more personalized implants can enhance precision through better adjustment dose profiles contours cancerous tissues. An original approach integrating biomedical imaging, 3D printing, radioactivity painting, and developed as a workflow development tumor...
This study reports the comparison between two dose calculation algorithms, Acuros XB 13.5 (AXB) and Analytical Anisotropic Algorithm (AAA) against Monte Carlo (MC) simulations for 3D-Conformal Radiation Therapy (3D-CRT) using a female pelvic rando phantom. 3D-CRT treatment plans were generated on CT images of phantom AXB AAA with Source to Axis Distance (SAD) technique. Doses obtained algorithms MC results compared MATLAB based software CERR. In house code was developed calculate gamma...
Nanoparticles (NPs) with radioactive atoms incorporated within the structure of NP or bound to its surface, functionalized biomolecules are reported as an alternative low-dose-rate seed-based brachytherapy. In this study, authors report a mathematical dosimetric study on low-dose rate brachytherapy using NPs.Single-cell dosimetry was performed by calculating cellular S-values for spherical cell model Au-198, Pd-103 and Sm-153 NPs. The survival tumor volume versus time curves were calculated...
Modeling of linac head (VARIAN Trilogy) for 6 MeV photon beam was performed using BEAMnrc code package (BEAMnrc 2017). The DOSXYZnrc used to determine the percentage depth dose (PDD profiles) and profiles different symmetric square field sizes, i.e., 5cm X 5cm; 40cm 40cm. DICOM images Alderson Radiation Therapy (ART) RANDO Phantom used. Four 3D-CRT treatment plans were generated AAA, PBC, Monte-Carlo (MC). It found that nominal energy 5.7 with FWHM 1.2 mm provides best matching modelled...
