Development of a Monte Carlo computational software and its application in Medical physics — •Milena Živković and Dragana Krstić — University of Kragujevac, Kragujevac, Serbia

The FOTELP-VOX code (author R. Ilić), with its advanced Monte Carlo techniques and precise dose distribution analysis, serves as a versatile tool applicable not only to particle transport simulations but also to the field of radiotherapy, including the specific application of the gamma knife. The software*s adaptability allows for its integration into radiotherapeutic practices, contributing to optimizing radiation treatments with a high degree of precision. The capability to model radiation interactions within the human body, coupled with the flexibility to customize parameters such as beam type, shape, and energy levels, positions FOTELP-VOX as a valuable asset in the planning and refining of radiotherapeutic interventions. For post-simulation analysis, the deposited energies, measured in either MeV/kg or Gy, are recorded in the REDOSE.TXT and SLIKA.DAT output files. These files, in conjunction with CT anatomy data, serve as the foundation for visualizing slices of the anatomy and the corresponding deposited doses in the individual voxels. In summary, FOTELP-VOX*s versatility makes it a powerful tool not only for general radiotherapeutic applications but also for addressing the unique challenges and requirements of gamma knife procedures, ultimately aiding in improving patient outcomes.
