[ 1 ] - Synthesis and characterization of nano Bi2O3 for radiology shield
Objective (s): Recently, the use of nanoparticles in medicine has increased for radiation protection purpose. So the aim of this study was application of nano Bi2O3 in prepared shield for dose reduction during medical imaging.Materials and Methods: Nano Bi2O3 shield with 90% silicon and 10% nano Bi2O3 was prepared and dosimetry test was down in radiology by PTW DIADOS E dosimeter.Results: The m...
[ 2 ] - Fabrication of New 3D Phantom for the measurement of Geometric Distortion in Magnetic Resonance Imaging System
Introduction: Geometric distortion, an important parameter in neurology and oncology. The current study aimed to design and construct a new three-dimensional (3D) phantom using a 3D printer in order to measure geometric distortion and its 3D reproducibility. Material and Methods: In this study, a new phantom ...
[ 3 ] - Comparing X-ray dose reduction capability of silicon-bismuth micro- and nanocomposite shields using chest CT test
Comparison of radiation shields of different thicknesses and structures (especially different particle sizes of their constituents) is helpful to select an appropriate shield for patient protection in medical imaging tests particularly CT-scan. In this study micro- and nano-powders of bismuth were mixed with silicone matrix to make composite radiation shields for breast. The shields were provid...
