Intended Use / Indications for Use
Lightning Viewer is software for diagnostic and clinical review intended for use in General Radiology (images from modalities including CR/DR/XT, CT, FL, MR, MG, NM, US/US Echo, PET, VL) and other healthcare imaging applications.
Lightning Viewer is intended to be used with off the shelf computing devices. Display monitors used for reading medical images for diagnostic purposes must comply with applicable clinical requirements, regulatory approvals, and with quality control requirements for their use and maintenance. With appropriate display monitors, lighting, image quality, and level of lossy image compression, Lightning Viewer is intended for diagnostic purposes to be used by trained healthcare professionals. Display calibration and lighting conditions should be verified by viewing a test pattern prior to use for diagnostic purposes.
Lightning Viewer supports major desktop browsers such as Microsoft Edge, Chrome, Safari, and Windows. Lightning Viewer displays both lossless and lossy compressed images. Each healthcare professional must ensure that they have the necessary environment to ensure the appropriate image quality for their clinical purpose and determine the level of lossy image compression acceptable for their purpose. Lossy image compression should not be used for primary reading in mammography.
Lightning Viewer can be utilized for image manipulation by radiology technologists or other healthcare professionals. Lightning Viewer can be used to verify that images captured in a medical imaging system have a diagnostic quality: to correct viewing characteristics of the image such as orientation, rotation, and contrast; as well as to add annotations to mark significant findings or provide guidance for radiologists.
Lightning Viewer can store annotations and measurements as DICOM presentation states without changing the original image data. Lightning Viewer can display annotations and measurements as an overlay on images from DICOM objects, and from Computer-Aided Diagnosis (CAD) and AI software. The viewer can perform 3D Multi-Planar Reformatting (MPR), 3D Maximum Intensity Projection (MIP) and 3D Volume Rendering (VR). Lightning Viewer is purposed to aid in reviewing findings through its ability to display clinical documents and reports side by side with the images. This can be used side by side with a reporting tool to create diagnostic reports.

9. PERFORMANCE DATA
9.1. Software Verification and Validation Testing
Software verification and validation testing were conducted, and documentation was provided as recommended by 2023 FDA Guidance "Content of Premarket Submissions for Device Software Functions".
The software verification and validation testing verified that the design requirements were successfully met. The intended use and user needs were successfully validated.
As the intended use, functionality and performance of the subject device and the predicate device are equivalent, the result of the performance testing is evidence that the Lightning Viewer performs in an equivalent manner to the OmegaAI Image Viewer.
9.2. Non-Clinical Performance Testing
A phantom study using a dataset with known voxel dimensions to evaluate the accuracy of the device's measurement calculations was performed and demonstrated that the device accurately calculates distance and angle measurements based on user-defined inputs.
9.3. Clinical Performance Testing
No clinical performance data was necessary to claim substantial equivalence.
10. CONCLUSION
The Lightning Viewer shares similar technological characteristics, intended use, and functionality with the predicate device. There are no differences between the devices that raise new questions of safety and effectiveness.
Furthermore, non-clinical performance test data and software verification and validation demonstrate that Lightning Viewer performs comparably to the predicate device in terms of safety and effectiveness.
Based on the device comparisons and the acceptable testing results, it is determined that Lightning Viewer is substantially equivalent to the predicate device.
