Target coverage goals for the gross tumour volume (GTV) and planning target volume (PTV) on the ARREST clinical trial

Goal	Acceptable	Not acceptable
PTV: ≥95% of the PTV to receive ≥95% of the prescription dose for every lesion.	GTV: ≥95% of the GTV to receive ≥95% of the prescription dose for every lesion.	1. Failure to meet dose constraints listed in Additional file 1 2. Not being able to meet minimum “Acceptable” coverage for every lesion i.e. 3. < 90% of lesions meet the “Goal” target coverage criteria
