-
no inhomogeneity correction (CT/MRI/UH only in the background for
catheter/applicator reconstruction)
- assumption of full scattering condition (infinite medium)
-
no correction for source movement of HDR source (only dwell times)
- no correction for applicator/catheter absorption
- no correction for seed absorption
Limitations of TG-43 formalism
Model-based dose calculation algorithms (MBDCAs
) either explicitly simulate the transport
of radiation in the actual media or employ multiple dimensional scatter integration techniques
to account for the dependence of scatter dose on the 3D geometry.
