Chest x-ray images of patients with (mostly) PCR-positive COVID-19 are collected from different publicly available sources, such as SIRM. Please cite the associated paper if you are using CXR images. If this repo helped you with your research stuff, you can star it.

There are currently 900 images with different sizes and formats, and the data will not be updated anymore. Normal CXRs are collected from different datasets, without a pediatric image bias. Note that a - sign at the end of image name indicates that CXR did not reveal any abnormalities, but the patient had CT/PCR-proven COVID-19 infection (probably patient is in early stages of disease progression). Besides, a p letter at the end of image name means that the image is taken from pediatric patient.
