IMRT – Why?
IMRT or
Intensity-Modulated Radiation Therapy is a
technique that allows
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
.
• This can allow dose escalation.
• IMRT can
improve dose homogeneity.
• IMRT can facilitate
Simultaneous
integrated boost
(SIB).
