The problematic Minimum Target Dose or Minimum
Peripheral Dose:
In spite of the high sensitivity of the minimum dose MTD or minimum
peripheral dose MPD in the planning target volume against delineation
inaccuracies and the used resolution of the calculation grid or number
of sample points, these values are still in the national, European,
American and International Reports and Recommendations.
Due to the extended use of individual plan optimisation (prostate, Gyn,
breast, ...) utilising modern inverse optimisation tools in RTPs, the dose
prescription and distribution becomes
individual
and is now
the best
achievable compromise between PTV-related and OAR-related
objectives.
Thus we learned, that we have to distinguish between the
“aimed” or “intended” prescription dose to the PTV (protocol) and the
individually realised – “planned” prescription dose.
