Hybrid Phantom Applications to Nuclear Medicine
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...
Design and Development of a Combined EEG-NIRS Phantom
Introduction
Tissue mimicking phantoms are used in optical imaging and for spectroscopic studies
because they allow to perform experiments with arbitrary an well known optical properties
under controllable conditions...
A spatial sensitivity mapping phantom for NIRS-signal interpretation
of such biological structures and processes and to study them and their influence on the signal independently and under controlled conjoint conditions. This is possible with a physical phantom.
Objective
Creation of a physical phantom, which allows...
شبیه سازی مدل کامل سر و گردن انسان بزرگسال و محاسبه دز دریافتی در اسکن تیروئید
According to the daily lives of the rays (used in industry,medicine, power generation,etc.) access to the best ways dosimetry becomes very important. Ionizing radiation have adverse biological effects on the cells.To ...
Development of 9-month pregnant hybrid phantom and its internal dosimetry for thyroid agents
Due to fetal radiosensitivity, the estimation of internal dose received by fetus from radiopharmaceuticals incorporated to the mother is often important in nuclear medicine. A new 9-month pregnant phantom based on magnetic resonance (MR) images tied...
FLUKA simulation studies on in–phantom dosimetric parameters of a LINAC–based BNCT
The Monte Carlo simulation code, FLUKA version 2011.2c.5, has been used to estimate the in–phantom dosimetric parameters for use in BNCT studies. The in–phantom parameters of a typical Snyder head, which are necessary information prior to any...
Which Body Model Is More Suitable for Dosimetry Calculations?
Computational phantom(three dimension computer models of human body) are essential in estimating organ doses from various occupational radiation exposures and medical procedures. Mathematical phantoms use mathematical equations to describe...
Hybrid pregnant reference phantom series based on adult female ICRP reference phantom
This paper presents boundary representation (BREP) models of pregnant female and her fetus at the end of each trimester. The International Commission on Radiological Protection (ICRP) female reference voxel phantom was used as a base template...
Assessment of Dose Distribution from I-131 and I-123 Sodium Iodide Administration for Voxel Phantoms
The organ doses from administration of Iodine-131, Iodine-123 sodium Iodide was calculated for the reference voxel phantoms by using the Monte Carlo transport method. Besides, the dose distribution in the body was obtained in 3D contour plots...
Population of whole-body statistical adult phantoms and assessing the uncertainty of organ doses in hyperthyroid treatment with 131I
In this paper, a series of computational phantoms (males and females) were developed based on computed tomography (CT) images of a healthy Iranian population. The Monte Carlo calculation method was then used to estimate organ doses...
