wobbling, scanning

1. Should we learn about the
Proton Treatment Method?

2. “
”
Wobbling? Scanning?
What
is
the
difference
between
the
two?

3. The
proton
beam
that
is
produced
from
the
accelerator
has
a
thickness
of
about 3mm

4. However,
the
size
of
the
tumor
are
all
different

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
beam
of
a
pencil
thickness
transferred
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.

보다 정밀한 치료가 가능합니다
The
Proton
Center
at
the
Samsung
Medical
Center,
is
the
second
place
in
the
world
whereultrahigh
speed
line
scanning
treatment
is
possible.
By
placing
a
dot
on
the
tumor,
the
scanning
beam
can
transfer
radiation
closest
to
the
3
dimensional
shape
of
the
tumor
with
thin
and
precise
beams,
similar
to
drawing
a
picture

12. Similar
to
a
3D
printer
that
makes
figures

13. When
designing
the
treatment,
the
Proton
Center
takes
into
account
the
patients
conditions
and
treatment
objectives
to
select
one
of
the
two
treatment
methods
in
order
to provide
most
suitable
treatment
to
the
patient
