Abstract :
Annually, many people are irradiated for diagnostic and therapeutic purposes. Assessment
of radiation dose and its related risks to patients are important issues in radiation
protection dosimetry. The complex mathematical calculations of the absorbed
and effective doses are now done with computers. The calculations are performed
with the help of anthropomorphic computational models of human body called phantoms
and Monte Carlo codes (MCNP). There are various types of phantoms, yet the
latest type is hybrid phantom which has been introduced to the scientific community
in recent years. Hybrid phantom is the connection between mathematical and voxel
phantoms. They retain both the anatomic realism of voxel phantoms and the flexibility
of mathematical phantoms. Using hybrid phantoms, the absorbed doses can
be determined for any patients before they are exposed to radiation. Then, the energy
of the emitted particles and irradiation geometry can be determined for any special
purposes. A hybrid phantom is under construction for Iranian patients to be used in
different applications such as testing new radiopharmaceuticals or cancer treatments
with high LET radiation. Herein, we report on our findings.
