Abstract

The FOTELP-VOX program is a Monte Carlo simulation tool designed for precise radiation dose calculations in medical physics. It allows for the accurate modeling of photon, electron, and positron transport through human tissues by using CT scan data to define patient anatomy. This study presents the application of FOTELP-VOX in simulating absorbed dose distributions in various clinical scenarios, including radiotherapy treatment planning for salivary gland tumors, eye melanoma and breast cancer. The results demonstrate the program's capability to replicate complex dose distributions with high accuracy, in comparison with clinical techniques like volumetric modulated arc therapy and 3-D conformal radiotherapy. FOTELP-VOX 2024 has demonstrated excellent performances when compared to clinical center results, showing a variation of only 5-8 %, which confirms its accuracy in simulating dose deposition and treatment planning. There is also the potential for incorporating optimization techniques to further enhance the precision and efficiency of radiotherapy treatment planning, contributing to improved patient care outcomes.

Key words: FOTELP-VOX, Monte Carlo simulation, radiation therapy, absorbed dose, CT data, dose distribution
