Stochastic vs. Deterministic Methods
 Stochastic (MC)
 Particle tracking process
 Errors come from insufficient
number of interactions
simulated and voxel size
 Stochastic errors
 Low efficiency in large
attenuation regions and volumes
 Parallelization
 Deterministic (AXB)
 Provides full solution of photon
and electron fluence
 Errors come from insufficient
refinement of discretized
variables
 No statistical noise
 High efficiency in large
attenuation regions and volumes

 Stochastic and deterministic methods:
 both converge to the same solution
 same accuracy
