Recent Trends in Photon Dose Calculation
 Boltzmann (1872) described the statistical
behavior of a thermodynamic system not in
equilibrium.
 A fluid with spatial temperature gradients is
a classic example.
 Modern applications to any kinetic equation
that describes the change of a macroscopic
quantity in a thermodynamic system, such
as energy, charge or particle number.
 Monte Carlo is a numerical method using
random sampling to approximate a solution.
 Discrete ordinates is a means of directly
calculating the average/probability of a
collection of particles evolving to a state of
positions and momenta over time.
