Technical Plan Comments

Example case shown planned with this RapidPlan model

  • The model is designed to be used for treatment plans of single lesions of the Liver.
  • The model was developed for patients with primary liver cancer but could be used also for metastatic patients with similar geometric conditions
  • The model supports a single target structure and was designed for a dose prescription of 5 fractions of 10 Gy per fraction
  • The dose-volume constraints at the basis of the cohort of plans used for the model training were derived from the NRG-GI003 clinical trial (NCT03186898 at clinicaltrials.gov)
  • The scientific reference for this model is:  Cozzi et al. Strahlenther Oncol. 2020. doi: 10.1007/s00066-020-01664-2
