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
