Dose in the redistributed radiotherapy regimen. Transverse (left) and coronal (right) view with isodose lines. In the dose-painted redistriburtion radiotherapy regimen, the GTV-FDG-PET is defined by an automatic iso-contour at 50% of the maximum uptake in the primary tumour. This is expanded by 3mm to form the PTV-FDG-PET. The GTV-primary should at least encompass the GTV-FDG-PET and is expanded by 10mm to form the PTV-primary. The PTV-FDG-PET will receive 35 fractions to a maximum total dose of 84 Gy to 2% of the volume (PTV-FDG-PET), a minimum dose of 70 Gy and a mean dose of approximately 77 Gy. The PTV-primary outside the PTV-FDG-PET will receive 35 fractions to a total mean dose of 67 Gy (ranging from 64-70 Gy).
