Course book Advanced Treatment Planning 2018

Suggestions

• Single phase (i.e. SIB) - 54Gy to PTV1, 70.2Gy to PTV3 in 39# ➢ (original as 2 phase plan - 54/30# to PTV 1 + 16.2/9# to PTV3) • S&S IMRT : 9 beams (maybe non-coplanar ?) • VMAT: at least 2 full arcs for PTV1 & PTV3 or sequential half arcs for PTV3 • Put priority on PTV coverage • Slightly turn collimator (20-30 degrees)

• Use aiding structures for getting the dose gradients exactly where you want them Good luck!
