The Prism Program

The Statistics panel

The Statistics panel comprises a table with information regarding the quality of the plans selected in the DVH panel.

The following criteria are displayed:

D₁₀₀	Dose that covers 100% of the PTV/CTV or organ, i.e. the minimal dose
D_Mean	The mean dose
D_Max	The maximum dose
D₉₅	Dose that covers 95% of the PTV/CTV
V₁₀₀	Percentage of the PTV/CTV that receives the prescribed dose
RCI	Radiation Conformity Index, ratio between the target (PTV) and the irradiated volume

Note D₉₅ and V₁₀₀ can only be attributed for target volumes (PTV, CTV), for organs the readouts are set to “n.a.”, denoting “not applicable”.
