ClearRead Xray Pneumothorax is a notification-only triage workflow tool for use by trained professionals to help prioritize chest X-rays. The device operates in parallel to and independent of standard of care image interpretation workflow. Specifically, the device uses an artificial intelligence algorithm to analyze images for features suggestive of a pneumothorax 5 mm or larger; it makes case-level output available to a PACS/workstation for worklist prioritization or triage. Identification of suspected cases of a pneumothorax is not for diagnostic use beyond notification. ClearRead Xray Pneumothorax is limited to analysis of imaging data as a guide to possible urgency of adult chest X-ray image review, and should not be used in lieu of full patient evaluation or relied upon to make or confirm diagnoses. The device does not replace review and diagnosis of the X-rays by trained professionals. The device is not intended to be used with plain film X-ray.
