I'm dr. sindu polka ellicott consultant
radiation oncologist working at Manipal
Hospital Bangalore so I am RT or
intensity modulated radiation therapy is
one of the most advanced forms of
tradition in imrt each radiation beam is
subdivided into hundreds of small beams
or which are known as beam 'lets in
density of our strength of each of this
beam which can be modulated or modified
by using various be modifying devices
known as multi leaf kilometers or a
menses
so I am are T is of particularly it is
valuable or useful in creating some
targets with either a concave or complex
shape or with close proximity to
radiosensitive nearby structures
this technique is mainly useful in
situations either we have to give a very
high dose of radiation to the tumor or
target example carcinoma prostate or
prostate cancer or where we have to
restrict those to addison critical
radiosensitive vital organs example a
sin had any concern that the spinal cord
will be coming in close proximity to the
tumor or target I Amata can be delivered
by two mechanisms either the MLCs can
move and treat this is known as a
dynamic mode also known as a sliding
window mode or MLCs will remain static
will acquire some specific shapes and
treat which is known as a static or
segmented MLC mlc technique i Amata can
also be used for intensity modulated arc
treatment as well
