Advanced Physics for Brachytherapy 2018

Why Follow the TG-43 Dose Calculation Formalism?

• Accurate interpolation of dose distribution is achieved because geometric dependence of dose falloff (as function of r and θ ) is accounted for. This allows use of a limited dataset while providing robust dose calculation.

• Analytic, uniform approach to brachytherapy dose calculation is readily available, thereby promoting consistent clinical practice worldwide.
