Cobalt (Co) doped zinc oxide (ZnO) microcrystals (MCs) are prepared by using the hydrothermal method from precursor's mixture of chloride (ZnCl2), cobalt-II hexahydrate (CoCl2·6H2O), and potassium hydroxide (KOH). The smooth round cylindrical morphologies synthesized Co-doped ZnO show an increase in absorption with cobalt doping. antibacterial activity as-obtained ZnO-MCs was tested against bacterial strains gram-negative (Escherichia coli, Klebsiella pneumonia) gram-positive bacteria...
Tissue equivalent materials (TEM) are frequently used in research as a means to determine the delivered dose patients undergoing various therapeutic procedures. They routine quality assurance and control procedures diagnostic physics. However, very few that tissue have been developed for use at low photon energies involved diagnosis radiology. The objective of this study is describe series TEMs designed radiographically imitate human energies. adipose, cortical bone, fat, lung, muscle...

Deterministic particle transport codes usually take into account scattered photons with correct attenuation laws and application of buildup factor to incident beam. Transmission factors for adipose, bone, muscle, skin human tissues, as well various combinations these media point isotropic photon source energies .15, 1.5 15 MeV, different thickness layers, were carried out using Geant4 (version 10.5) simulation toolkit. Also, we performed the analysis existing multilayered shield fitting...
The computational voxel phantom 'High-Definition Reference Korean-Man (HDRK-Man)' was implemented into the Monte Carlo transport toolkit Geant4. model, adjusted to Korean Man, is 171 cm in height and 68 kg weight composed of ∼30 million voxels whose size 1.981 × 2.0854 mm3. Geant4 code then utilised compute dose conversion coefficients (DCCs) expressed absorbed per air kerma free for >30 tissues organs, including almost all organs required new recommendation ICRP 103, due a broad parallel...
The aim of this study is to measure reader agreement for i) lesion classification and ii) breast density in Contrast Enhanced Mammography (CEM). Methods: Two experienced two inexperienced CEM readers reported 60 examinations. Kappa was used assess inter-reader between (benign/malignant) (dense/non-dense). Weighted kappa BI-RADS categories (1-5) (A-D). Intraclass correlation coefficient (ICC) measured using Visual Analog scale (VAS). Intra-reader one after a three month interval. Results:...
Quantification of scattered photons in addition to unscattered primary particles, under realistic exposure scenario, is best dealt with a parameter called "Buildup factor". The aim this work simulate the transmission buildup factor (BUF) gamma-ray energy range .15-15 MeV for 20 human tissues and organs using Geant4 (version 10.5) Monte Carlo simulation followed by geometrical progression (GP) parameterization procedure. Firstly, we verified accuracy ability predict effective transmitted dose...
Breast density is an important risk factor for breast cancer and has a substantial effect on the sensitivity of mammography screening. This study aimed to evaluate intra inter reader variability visual assessment in Saudi Arabia, using American College Radiology (ACR) Imaging Reporting Data System (BI-RADS) categories (5th edition) Visual Analogue Scales (VAS). A random sample 102 screening mammograms from National Cancer Screening Programme (SNBCSP) was assessed twice by two consultant...
