The subject device and the predicate device have intended use, operating principles and similar technological characteristics. The subject device differs from the predicate in software features, which include automatic alignment and motion correction. Additionally, minor changes were made through letter-to-file to both the software and hardware of the minor changes to the software included updates to the user interface and enhanced security features, and the minor changes to the hardware included modifications to the RF shield and screen, gauss guard, and battery charger through. These differences do not raise new questions of safety and effectiveness as compared to the predicate.

#### Non-Clinical Performance

The subject device has similar technological characteristics as the predicate (K201722) and differs only in software, which includes automatic alignment and motion correction features, updates to the user interface, and enhanced security features. As part of demonstrating substantial equivalence to the predicate, a risk analysis was completed to identify the risks associated with the software modifications. Performance testing was conducted to evaluate the modifications. The subject device passed all the testing in accordance with internal requirements and applicable standards to support substantial equivalence.

- Software Verification per IEC 62304:2006 and as recommended in the FDA Guidance, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices"
- Cybersecurity Information provided as recommended in FDA Guidance, "Content of Premarket Submissions for Management of Cybersecurity in Medical Devices"

The following testing was leveraged from the predicate device (K201722). Test results from the predicate were used to support the subject device because the conditions were identical or the subject device modifications did not introduce a new worst-case configuration or scenario for testing.

- Biocompatibility per ISO 10993-1:2018
- . Electrical Safety, EMC and Essential Performance per ANSI/AAMI ES 60601-1:2005/(R)2012, IEC 60601-2-33:2015, and IEC 60601-1-2:2014
- Electrical Safety Collateral Standard: Usability per IEC 60601-1-6:2013
- NEMA MS 1-2008 (R2014) - Determination of Signal-to-Noise Ratio (SNR) in Diagnostic Magnetic Resonance Imaging
- NEMA MS 3-2008 (R2014) - Determination of Image Uniformity in Diagnostic Magnetic Resonance Images
