CT images of popular face masks

The Sars-CoV-2 virus spreads through respiratory droplets released by infected individuals. Because of this many countries created mandates to wear face masks in order to limit the chance of spreading an infection.

This study observes the efficacy of these facemasks against the virus, as there have been many ongoing debates on how well the facemasks work to slow down the growth of the epidemic. The study was examined using X-ray computed tomography and infrared thermal imaging techniques, to perform image-based simulations of the flow of respiratory droplets that pass through different porous materials on the masks.
