ESTRO course Dose Modelling and Verification 2017



Now we have the means to characterise uncertainty – how does that

apply in comparing calculated and measured doses?



Fact

: There is a True dose at every point in an irradiated object.



We estimate this dose with measurement or models



Can assign a tolerance to individual points or to a set of points



=|Ave Deviation| + 1.96

Confidence Limit (Venselaar) (CI=95%, P=0.05)



See TK lecture for details



Need to set Tolerance and Action limits and its relation to the

uncertainty of measurements
