Abstract:
In this
paper,
the
proton
therapy
system
was
simulated
using
the
MCNPX
code,
and an
analysis
of the
dimensions
of the
resulting
radioactive
field
and dose
distribution
within
the
radiation
field
was
conducted
using
the
double
beam
scattering
technique.
The
energy
deposited
in terms
of depth
was also
studied
within a
water
phantom
with
dimensions
of
11×11×30
divided
into
elemental
volumes,
each
measuring
1x1x0.4.
This
analysis
was
performed
using a
modified
acceleration
for
range,
where
each
cycle of
the
modified
wheel
was
divided
into 25
steps,
with
each
step
represented
by an
equivalent
thickness
of lead
and
Lexan.
The
study
revealed
the
possibility
of
obtaining
a
radioactive
field
with
dimensions
of 7 x 7 ,
concentrating
about
95% to
100% of
the
maximum
dose.
Additionally,
it was
also
found
that the
dose
distribution
can
extend
to a
depth of
20 cm
within
the
phantom.
