Hybrid Phantom Applications to Nuclear Medicine

Annually, many people are irradiated for diagnostic and therapeutic purposes. assessmentof radiation dose and its related risks to patients are important issues in radiationprotection dosimetry. the complex mathematical calculations of the absorbedand effective doses are now done with computers. the calculations are performedwith the help of anthropomorphic computational models of human body called phantomsand monte carlo codes (mcnp). there are various types of phantoms, yet thelatest type is hybrid phantom which has been introduced to the scientific communityin recent years. hybrid phantom is the connection between mathematical and voxelphantoms. they retain both the anatomic realism of voxel phantoms and the flexibilityof mathematical phantoms. using hybrid phantoms, the absorbed doses canbe determined for any patients before they are exposed to radiation. then, the energyof the emitted particles and irradiation geometry can be determined for any specialpurposes. a hybrid phantom is under construction for iranian patients to be used indifferent applications such as testing new radiopharmaceuticals or cancer treatmentswith high let radiation. herein, we report on our findings.
