InferRead DR Chest is a screening tool that analyses chest radiograph DICOM images from medical imaging storage devices and automatically evaluates the probability of an abnormality suggestive of tuberculosis (TB). It shows the abnormal cases in a study list. InferRead DR Chest is used to assist doctors in the diagnostic process, but should not be used as a confirmatory diagnostic tool on its own. The InferRead DR Chest product offers different deployment configurations that adapt to different use cases.
