Meaningful dose constraints
Current dose constraints based on non-adaptive plans (ie 45 Gy maximum dose
to GI structures in hypofractionated regimen; 33 Gy to proximal GI
structures in SBRT regimen)
These are not necessarily applicable to a ‘plan of the day’ regimen
There are residual errors in the ‘plan of the day’ regimen
We will need to increase these tolerances to make a ‘real’ dose constraint
