The pseudocode of GPU-accelerated Monte Carlo method for dose calculation of mesh-type computational phantoms

Introduction to the Pseudocode for the GPU-Accelerated Monte Carlo Method for Dose Calculation in Mesh-Type Computational PhantomsThis document presents the pseudocode framework for a GPU-accelerated Monte Carlo (MC) program designed for dose calculation in mesh-type computational phantoms. The program workflow begins with reading the input parameters, initializing the physical model and geometry, and constructing the acceleration structure from the mesh model. It proceeds by invoking GPU kernel functions to parallelize the transport and interaction of particles within the tetrahedral mesh model. Finally, the simulation results are accumulated and reported.The pseudocode includes key support functions and relevant data structures, with a primary focus on handling the transport process of individual particles.
