Abstract :
Correlated sampling is evaluated as a strategy for accelerating Monte Carlo photon transport (MCPT) simulation for use as a practical patient-specific treatment-planning tool. Correlated MCPT simulation was shown to offer substantial efficiency gains over conventional MCPT simulation for selected parts of the 3D volume but was not sufficient to improve MCPT simulation everywhere
