Modern Bt Techniques - Florence 2016

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.
