COVID-19 CT & X-ray Image Data Stock

Covid 19 CT & Radiograph Image Data Stock

The aim of COVID-19 CT & X-ray Image Data Stock is to create a public pool of CT and X-ray images of lungs to increase the efficiency of distinguishing COVID-19 from other types of pneumonia and from healthy lungs. We hope this can help to prepare a "ground" for distinguishing between newly discovered and already known viruses and bacteria strains causing pneumonia in order to improve diagnostics
in the event of subsequent pandemics. For this reason we included COVID-19-negative samples of several classes which include healthy chest (negative control) and various types of pneumonia (bacterial, fungal, viral). The images which constitute COVID-19 CT & X-ray Image Data Stock were compiled from public sources. Most of the images come from websites with image collections and about 150 images were collected from online publications.
The attributes in a data stock are shown in the table below (Table 1).

The database prepared by us is available for everyone registered in Image Service.
Until the inhibition of COVID-19 pandemic, the database will be updated monthly.

IMPORTANT NOTE: Registration to Image Service is free.
