Abstract:

Monte Carlo simulation plays a key role in both research and clinical practice; it has become an essential tool in dosimetry in modern brachytherapy to determine dose distributions around radioactive source. The measurements of absorbed doses in organs are required to protect it against any type of ionizing radiation, but implantation dosimeters inside human body organs is impossible that makes the dose measurements not measurable. The use of mathematical human body phantom with exact description of organ geometry, tissue chemical constitution, and appropriate computer program can predict the amount of doses delivered to each organ inside human body. The virtual patient is ORNAL woman heterogeneous phantom and other with homogeneous phantom, both two phantoms underwent MammoSite balloon brachytherapy for left breast with 11 dwell positions.
