Quality of Thorax CT Scan Images among Covid-19 Cases using Variations of Filter

A typical image of the Thorax CT Scan as a sign of the early stages and development of Covid- 19 is the finding of Ground Glass Opacities (GGO). GGO is an insignificant increase in the density of the lungs without occlusion of blood vessels and bronchi. In mild cases, GGO tends to be difficult to identify and requires high-resolution CT scanning. In this study, we intend to improve the reso…
