Device Story
RadUnity is a standalone software device (SaMD) for centralized management, standardization, and reformatting of CT images. It ingests DICOM CT volumes from PACS or modality units; processes them via user-defined 'Profiles' (e.g., filtering, smoothing, edge enhancement, MPR, MIP, MinIP); and routes the standardized output to DICOM destinations. Operated by radiology professionals in clinical settings, it automates workflow steps to ensure consistent image formatting for downstream interpretation. It does not perform primary diagnostic review. The system requires manual user interaction to generate and route images. By standardizing image presentation, it facilitates efficient clinical workflows for qualified clinicians.

#### (Per 21 CFR 807.92)
Radunity processes industry standard DICOM imaging studies. Currently, the RadUnity solution only processes computed tomography (CT) images. The data may flow into the system from PACS, a post-processing system, or any DICOM node (e.g., directly from a modality unit). The data is transferred for image processing and standardization. The data is then routed to user defined DICOM destinations and output in DICOM format.
RadUnity is fundamentally a workflow management system which performs image processing and standardization which allows the clinical user to view the CT images with consistent formatting.
RadUnity provides the user with the ability to duplicate current clinical workflow steps required to generate images for qualified clinician interpretation that may involve automatic or manual steps. The RadUnity solution requires manual user interaction to generate and route images to DICOM destinations for qualified clinician interpretation.
The input DICOM images needed for RadUnity are referred to as "source volumes". These source volumes are commonplace in the radiology community today (e.g., lung or bone reconstructions) and contain the needed information to create soft tissue and other thicker slice and lower resolution image volumes.
