Analytical Methods for Photon Beam Calculation
Early methods of dose calculation Based on separating the dose into primary and scatter component using empirical methods (e.g. Clarkson scatter integration) Inhomogeneities were corrected by scaling the fluence/ dose with density (Equivalent Path Length method, Ray Tracing ...) Works well if electron transport and effect of inhomogeneities on scatter component can be ignored
