Summary of Technological Characteristics Comparison FlexView Diagnostic and ZeeroMED View share equivalent intended use and functionality, as well as similar web technologies. Both systems allow access, upload, and display of DICOM images and metadata, and provide tools and resources for physicians to review studies. Additionally, both systems are hosted on web servers and are equipped with security features and user authentication. Both devices offer similar features such as window/level adjustments, image view controls (rotate, pan, and zoom), measurement functions, text annotations, report generation and DICOM windowing. Additionally, both devices can connect to existing PACS systems and store, display, and transfer medical images. Both devices also support the same imaging modalities, including US, CT, MRI, and X-Ray. There are several minor differences in technological characteristics between the two devices: - The predicate device has a "Share Function," which enables remote, real-time . collaboration among multiple users. This feature is not currently supported by the subject device. - The predicate device supports Mac, Windows, and Linux operating systems, while the ● subject device only supports Mac and Windows. - The predicate device supports Chrome, Edge, and Firefox browsers, while the subject . device supports Chrome, Edge, and Safari. {9}------------------------------------------------ Image /page/9/Picture/0 description: The image is a square with a dark blue background. In the center of the square is a small white square. Surrounding the white square are four light blue L-shaped figures, one in each corner of the square. The L-shaped figures are oriented so that they appear to be pointing towards the center white square. The lack of features (e.g., share function, Linux OS compatibility, and Firefox compatibility) in the subject device that are found in the predicate device is not a concern relating to safety or effectiveness, as these are not required to meet the device's intended use. Similarly, the presence of additional features (e.g., compatibility with additional internet browsers) in the subject device that are not found in the predicate device does not raise any new questions of safety and effectiveness and have been properly verified through testing. ## 7. DISCUSSION OF NON-CLINICAL TESTING FlexView Diagnostic was subjected to the following non-clinical testing. ### 7.1. Software Verification and Validation Software verification and validation testing were conducted on the Flex View Diagnostic system and documentation was provided as recommended by FDA's 2023 Guidance for Industry and FDA Staff, "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, indications, functionality and performance of Flex View Diagnostic and the ZeeroMED View are equivalent, the result of the non-clinical performance testing is evidence that the subject device performs in an equivalent manner to the predicate device. ### 7.2. Measurement Accuracy Verification of Flex View Diagnostic included manual testing of the measurement tools (length, bidirectional and angle measurements) using phantom (calibrated and uncalibrated) DICOM images. Measurement accuracy testing involved evaluating the difference (i.e., delta) between the expected length and the measurement entered by the user. Delta results were calibrated to +/- 1 units, which is equivalent to +/- 1 units relative to the acquisition size and display resolution. This calibration ensured consistent accuracy across different zoom levels. Acceptance criteria for this test included statistical analyses such as mean, standard deviation, standard error and a one tailed t-test. Verification testing for all measurement tools passed the predetermined acceptance criteria. {10}------------------------------------------------ Image /page/10/Picture/0 description: The image is a square logo with a dark blue background. In the center of the logo is a small white square. Surrounding the white square are four light blue shapes, each resembling a corner bracket, placed at the corners of an imaginary square centered on the white square. The corner brackets are oriented such that they appear to be framing the central white square. ### 7.3. Conclusion The subject device 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 FlexView Diagnostic 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 FlexView Diagnostic is substantially equivalent to the predicate device. --- **Source:** [https://fda.innolitics.com/submissions/RA/subpart-b%E2%80%94diagnostic-devices/LLZ/K233226](https://fda.innolitics.com/submissions/RA/subpart-b%E2%80%94diagnostic-devices/LLZ/K233226) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
