Note CI not a “fair” comparison as dose is 95% of the lymph nodes, ie 70% of boost dose

IMRT – Why?

Intensity-modulated radiation therapy is a technique that allow confinement of the high dose region to that of the target volume .

• IMRT is a further development of conformal RT. • IMRT can conform to complex and in particular concave target volumes. • IMRT can avoid normal tissue . • IMRT can improve dose homogeneity. • IMRT can facilitate Simultaneous integrated boost (SIB).
