Evaluation of eye shields made of tungsten and aluminum in

Conclusions:Tungsten is superior to lead as a material for eye shields due to its higher density and lower atomic number (Z). Using 6- and 9-MeV electrons, tungsten provides the necessary protection for the lens and cornea of the eye and decreases the amount of backscatter to the eyelid above the shield.",

ASE Guidelines for the Protection of Echocardiography

Apr 14, 2020 · The provision of echocardiographic services remains crucial during the novel coronavirus (COVID-19, SARS-CoV-2) outbreak. To minimizing risks to cardiac ultrasound staff, The American Society of Echocardiography (ASE) commissioned a group of experts to a statement outlining recommendations to improve safety and reduce the potential for COVID-19 cross contamination.

Medical interventions for traumatic hyphema

Medical interventions for traumatic hyphema Traumatic hyphema is the entry of blood into the space between the cornea and iris following a blow or a projectile striking the eye. Along with the appearance of blood, there may be one or more major injuries to the eye from the trauma, which could result in a significant reduction in vision.

Bismuth shielding, organ-based tube current modulation

Increasing the distance between the bismuth shield and the eye lens helped reduce CT number errors, but the increase in noise remained. Conclusion:Organ-based TCM provided superior image quality to that with bismuth shielding while similarly reducing dose to the eye.
