Study of Analysis the Sensitivity of the Computational Environment for Radiological Research Field Size Based on Two Dimensional Dose Distribution for Water Phantom Cases.
Radiotherapy is one form of radiation therapy applications.
Therefore, treatment planning in
radiotherapy aims to produce a uniform dose
distribution to the target volume and minimize doses
beyond the target volume.
Some parameters that
need to be regulated are the number of radiation beams, the
radiation direction, the field
size used, and the radiation’s beam weight.
A technique known as intensity
modulated radiation therapy allows a
three dimensional dose distribution delivered to the patient.
Photon fluency is modulated in such a way
as using the multi-leaf collimator.
MLC can work continuously and alternately form
radiation exposure fields in
either regular or irregular forms. MLC is
used to block or allow radiation to
create a beam field size according to the tumor’s shape.
radiation therapy method has improved
accuracy and has led to a technique of
limiting tumor movement
In IMRT optimization, it is essential to note the conformation between
the level of accuracy and efficiency of the dose
Different dosage calculation algorithms
based on the IMRT technique are produced, including
Monte Carlo, and superposition/convolution.
