1. A method to facilitate the administration of therapeutic radiation to a heterogeneous patient volume using a radiation beam source, the method comprising:
determining a cross-sectional size of a radiation beam as corresponds to the radiation beam source;
generating a three-dimensional radiation dose calculation for the heterogeneous patient volume using a control circuit configured as a convolution/superposition based dose calculator using a three-dimensional energy-spreading kernel, wherein the calculator scales total energy released per mass as a function, at least in part, of the cross-sectional size of the radiation beam.
