The document discusses two proton treatment methods - wobbling and scanning. The wobbling method uses a thin plate to expand the proton beam, making it suitable for large tumors. The scanning method divides the proton beam intensity into several hundred parts to precisely apply the beam to the tumor size and shape, minimizing radiation exposure to surrounding tissues. This allows for more accurate radiation delivery according to the tumor shape. The document concludes that the scanning method is the most precise proton treatment option and is available at the Samsung Medical Center, which is one of only two facilities in the world that offers ultra-high speed line scanning treatment.
5. Therefore,
the
size
of
the
proton
beam
has
be
adjusted
to
the
size
of
the
tumor
6. But
how? Depending
on
how
the
proton
beam
is
used,
the
proton
treatment
method
is
divided
in
two
ways
7. First, the
Wobblingmethod
The
proton
beam
comes
in
contact
with
a
thin
plate
to
become
expanded
and
it
is
a
method
used
to
treat
large
tumor
sites
8. Second, the
Scanning
method
By
dividing
up
the
energy
intensity
of
the
proton
beam
from
several
into
several
hundred,
it
is
a
method
that
accurately
applies
the
proton
beam
to
the
corresponding
size
of
the
tumor
to
facilitate
a
more
precise
treatment
9. VS
Wobbling
Method
Using
the
block
and
compensator,
transfer
the
expanded
proton
beam
to
the
corresponding
tumor
shape
Scanning
Method
Proton

to
the
corresponding
tumor
shape
10. The
Scanning
method,
in
comparison
to
the
Wobbling
method,
it
has
an
advantage
of
transferring
sufficient
amount
of
radiation
to
the
tumor
while
minimizing
radiation
exposure
to
the
surrounding
normal
tissues
to
decrease
the
development
of
side
effects.
Particularly,
radiation
can
be
accurately
transferred
to
tumor
according
to
its
shape.
Therefore,
it
can
be
regarded
as
the
most
exquisite
proton
treatment
method.

The

is
the
second
place
in

whereultrahigh

is
possible.
By
placing
a
dot
on
the
tumor,
the
scanning

can
transfer
