Development of anthropomorphic computational phantoms at the UFPE

چکیده
To evaluate the amount of energy deposited in radiosensitive organs and tissues human body, when an anthropomorphic phantom is irradiated, researchers numerical dosimetry use so-called exposure computational models (ECMs). One can imagine ECM as a virtual scene composed mathematically defined position relation to radioactive source. The source these ECMs produces initial state simulation: position, direction, with which each particle enters are essential variables. For subsequent states history, robust Monte Carlo (MC) codes used. particle's used, simulate average free path that performs without interacting, its interaction atoms medium per interaction. MC also normalization quantities, so results printed text files form conversion coefficients between absorbed dose selected quantity. From 2000s, authors have published where voxel irradiated by photons environment code EGSnrc (EGS = Electron Gamma Shower; nrc National Research Council Canada). production articles, dissertations theses required specific tools, such FANTOMAS, DIP (Digital Image Processing) applications, for various steps dosimetry, ranges from preparation input execution organization graphical analysis results. This article reviews phantoms mainly those produced DEN-UFPE thesis.

Computational Anthropomorphic Phantoms for Radiation Protection Dosimetry: Evolution and Prospects
Phantoms for radiation dosimetry, including physical phantoms for radiological use in medicine in particular, were introduced as early as the 1910s [1] while those for radiation protection dosimetry started to evolve in the late 1950s. This innovation was driven partly from the consensus that dose quantity for protection purposes should be assessed in “receptor conditions” instead of the tradit...
متن کاملAutomatic Synthesis of Anthropomorphic Pulmonary CT Phantoms
The great density and structural complexity of pulmonary vessels and airways impose limitations on the generation of accurate reference standards, which are critical in training and in the validation of image processing methods for features such as pulmonary vessel segmentation or artery-vein (AV) separations. The design of synthetic computed tomography (CT) images of the lung could overcome th...
متن کاملDevelopment of a free anthropomorphic voxel model of human body for wide-band computational electromagnetics dosimetry
To calculate and evaluate wave scattering and penetration of electromagnetic waves in different biological tissues it is necessary to use a realistic model of the human body, with all tissues resolved and separately assigned with appropriate electric/magnetic properties. We report the development of a realistic 3D whole-body human model that has been adapted for simulation in CST software, cont...

The Radiological Physics Center (RPC) developed two heterogeneous anthropomorphic quality assurance phantoms for use in verifying the accuracy of radiation delivery: one for intensity-modulated radiation therapy (IMRT) to the pelvis and the other for stereotactic body radiation therapy (SBRT) to the thorax. The purpose of this study was to describe the design and development of these two phanto...
