Prescription

You can add multiple prescriptions for different target structures and all of them will be applied to the treatment plan. The plan re-normalization value can be used to scale the final plan level dose.

In the Prescription block you can set the following fields:

• Fractions : This is the number of fractions over which the prescription dose will be delivered.
• Prescriptions : This is the total prescription dose value in Gy (maximum of 100 Gy) and the target structure for said dose.
  • Note that at this time prescription values do not have an exact specified meaning (e.g. mean, min) as the ElectronRT application only uses these values to scale the relative dose to absolute dose in the UI. In the event of multiple prescriptions, the eRT application will use the first prescription statement to set the 100% relative dose value.
• Plan Re-Normalization : The value used to re-normalize the plan level dose.
