COMPUTATIONAL ANTHROPOMORPHIC PHANTOMS FOR RADIATION PROTECTION DOSIMETRY

摘要: Computational anthropomorphic phantoms are computer models of human anatomy used in the calculation radiation dose distribution body upon exposure to a source. Depending on manner represent anatomy, they categorized into two classes: stylized and tomographic phantoms. Stylized phantoms, which have mainly been developed at Oak Ridge National Laboratory (ORNL), describe by using simple mathematical equations analytical geometry. Several improved such as male female adults, pediatric series, enhanced organ following first hermaphrodite adult phantom, Medical Internal Radiation Dose (MIRD)-5 phantom. Although significantly contributed dosimetry calculation, provide only approximations true anatomical features resulting distribution. An alternative class computational is based three-dimensional imaging techniques magnetic resonance (MR) computed tomography (CT). The with large number voxels that assigned tissue type identity. To date, total around 30 including even pregnant female, utilized for realistic calculation. They MRI/CT images or sectional color photos from patients, volunteers cadavers. investigators compared demonstrated superiority terms This paper summarizes history current status both Korean Advantages, limitations, future prospects also discussed.
