I will do monte carlo geant4 simulations for medical physics and radiation analysis

I specialize in advanced Monte Carlo radiation transport simulations using Geant4, with particular expertise in medical linear accelerator modeling for external beam radiotherapy applications. This project demonstrates a complete 6 MeV photon therapy beam simulation, incorporating realistic physics including bremsstrahlung production from electron-tungsten interactions, dual-stage collimation systems, and optional beam flattening filters for dose homogenization. The geometry includes proper radiation shielding design with lead backscatter protection and accurately models the complete treatment head assembly from primary target through exit window.

The simulation framework implements comprehensive dosimetric analysis capabilities including percent depth dose profiling, lateral beam profile measurements for quality assurance, and multi-particle energy spectroscopy for beam characterization. Three-dimensional dose distributions are captured through tri-planar heat mapping, enabling detailed visualization of spatial dose deposition patterns within water-equivalent phantoms. The code architecture supports dynamic gantry positioning with full Euler angle rotation kinematics and automated
