The start of coronavirus pandemic pushed limits of healthcare systems all over the world by causing thousands of deaths and the requirement of a huge quantity of healthcare resources. When WHO declared COVID19 as a pandemic, the whole world came to standstill. Half of the world population is confined to their home except for essential services. In the year 2016, when GOI announced ...
Magnetic resonance imaging (MRI) is a frequently used diagnostic imaging modality that may be an alternative to other types of radiologic imaging (e.g., computerized tomography, nuclear medicine imaging). It can detect soft tissue characteristics (e.g., inflammation), and because magnetic resonance (MR) uses a magnetic field and radio waves to produce images, it does not expose patients to ...
This paper presents a computer code for the assessment of absorbed effective doses and dose equivalents in X-ray diagnostics. The absorbed doses in a patient's tissues in various X-ray examinations were estimated using the Monte Carlo method. The X-ray spectra generated by the empirical TASMIP model were verified. Further simulations were based on an anthropomorphic phantom of a standard adult. ...
The non-cancer disease mortality (1950-1995) among 27 011 medical diagnostic X-ray workers was compared to that of 25 782 other medical specialists employed between 1950 and 1980 to provide evidence of human non-cancer disease death produced by protracted and fractionated exposure to ionising radiation and assess the resultant non-cancer disease death risk. The total non-cancer disease mortality ...
We examined the production of dicentrics in human lymphocytes irradiated with 29 kV X-rays to a depth of 13.5 mm in a PMMA phantom. For these irradiation conditions, which are appropriate for the diagnostic application of mammography X-rays, a coefficient of (5.88±0.66)×10–2 Gy–1 of the linear quadratic dose–response relationship was determined. This value does not differ significantly from the ...
