Abstract
The previous Monte Carlo codes offer the most powerful engines to study the processes physic of particles including their interactions in Radiation Therapy. In this task, we take benefit of GATE 8.2 to simulate the linear accelerator system, IAEA phase-space folders are exploited to speed up computing time. The model developed includes the majority of the components of the patient-dependent part using in Elekta 6MV platform. This model is used accompanied by a homogeneous water phantom with dimensions \( 50 \times 50 \times 50\) cm\(^{3}\), placed at an SSD of 100 cm. The comparisons of our results are performed with experiment data respecting the similar aspect. The Percentage Depth Dose (PDD) and transverse profiles, for field size of \( 10 \times 10\) cm\(^{2}\), are accurately calculated. Besides, the beam quality such as \( D_{10}\) (%), \( d_{max}\) (cm), \( d_{80}\) (cm), \(TPR_{20/10}\), the two relative differences in dose were derived on \(\psi _{i} \), \(\psi _{i,max}\) and the ratio \(\mathfrak {R}_{i}\) are calculated. Once and for all, we typically take a good agreement between simulation MC GATE 8.2 and the experiment data with an error less than 2%/3 mm.
