ESTRO course Dose Modelling and Verification 2017

Alt 1: Using Dose profiles & Output factors

• Dose profiles reshaped using factors deduced from first order, point source fluence changes

• Workhorse in old time “2D” TPS and some Monitor Unit Check programs

• OK for a limited set of field geometries at non-violated equilibrium conditions, e.g. stereotactical treatments

• Breaks down for general CRT/IMRT/VMAT conditions!
