Regulatory Classification

Identification

A medical image management and processing system is a device that provides one or more capabilities relating to the review and digital processing of medical images for the purposes of interpretation by a trained practitioner of disease detection, diagnosis, or patient management. The software components may provide advanced or complex image processing functions for image manipulation, enhancement, or quantification that are intended for use in the interpretation and analysis of medical images. Advanced image manipulation functions may include image segmentation, multimodality image registration, or 3D visualization. Complex quantitative functions may include semi-automated measurements or time-series measurements.

Special Controls

*Classification.* Class II (special controls; voluntary standards—Digital Imaging and Communications in Medicine (DICOM) Std., Joint Photographic Experts Group (JPEG) Std., Society of Motion Picture and Television Engineers (SMPTE) Test Pattern).

PERFORMANCE DATA The ATEC Alignment App was subjected to verification and validation testing in accordance with the functional requirements. Performance testing confirmed that the app accurately measures angles from x-ray images, and that resultant values are displayed properly with correct color-coded range. Angle measurements were verified within ± 2° accuracy. Validation testing was performed to confirm that the graphical user interface (GUI) and that data system features function as intended. A direct comparison test between the ATEC Alignment App and the Surgimap device using the same clinically representative images was conducted which concluded that the performance between the two devices was similar. The results demonstrate that the subject ATEC Alignment App is substantially equivalent to Surgimap 2.0 (K141669) and the NuvaLine Mobile App (K162647) and verifies that the subject device meets design specifications and performance characteristics based upon its intended use. ## Clinical Information Not applicable: determination of substantial equivalence is not based on an assessment of clinical performance data. #### VIII. CONCLUSION Based upon the information provided in this 510(k) submission. it has been determined that the subject device is substantially equivalent to the legally marketed primary predicate {7}------------------------------------------------ device (Surgimap 2.0, K141669) based on intended use, design, functionality, performance testing and other key technological characteristics.
