Description of the test set, sample size, data source, and annotation protocol
The additional engineering bench testing has successfully evaluated the performance of the DL Automatic kidney segmentation algorithm. The testing evaluated 70 planar NM renal studies acquired using GEHC systems from 2 hospitals in the United States and 1 hospital in Europe, serving a diverse patient population that include a range of ethnicities and demographics. The studies encompassed a range of dynamic renal clinical scenarios, detection technologies and collimators, tracers, scan parameters, and patient age. The studies were segregated, and not used in any stage of the algorithm development. The bench testing used the DICE similarity score to compare algorithm generated contours to ground truth (GT) contours, for evaluating performance against pre-defined acceptance criteria. The GT contours were reviewed and confirmed by an experienced Nuclear Medicine physician.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Bench Testing: The additional engineering bench testing has successfully evaluated the performance of the DL Automatic kidney segmentation algorithm. The testing evaluated 70 planar NM renal studies acquired using GEHC systems from 2 hospitals in the United States and 1 hospital in Europe, serving a diverse patient population that include a range of ethnicities and demographics. The studies encompassed a range of dynamic renal clinical scenarios, detection technologies and collimators, tracers, scan parameters, and patient age. The studies were segregated, and not used in any stage of the algorithm development. The bench testing used the DICE similarity score to compare algorithm generated contours to ground truth (GT) contours, for evaluating performance against pre-defined acceptance criteria. The GT contours were reviewed and confirmed by an experienced Nuclear Medicine physician. The DL Automatic kidney produced an average DICE score above the predefined success criteria.
Clinical Testing: The clinical testing evaluated the same 70 representative clinical exams, which were used in the additional bench testing. The results of the DL Automatic kidney Segmentation were evaluated by three qualified U.S. readers, who assessed the quality of the segmentation using a 4-point Likert scale. The readers evaluation demonstrated that generated segmentation was of acceptable utility, required minimal user interaction and supports the determination of substantial equivalence. All readers attested that the range of clinical cases reviewed in this evaluation provided adequate representation of the standard clinical practice and that the quality of the kidneys' segmentation generated by the algorithm was acceptable.
Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)
The bench testing used the DICE similarity score to compare algorithm generated contours to ground truth (GT) contours, for evaluating performance against pre-defined acceptance criteria. The DL Automatic kidney produced an average DICE score above the predefined success criteria.

Dear Hanne Jubran:
We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.

Determination of Substantial Equivalence
Summary of Non-Clinical, Design Control Testing
Aurora has successfully completed the design control testing per our quality system. No additional hazards were identified, and no unexpected test results were observed. Aurora was designed and is manufactured under the Quality System Regulations of 21CFR 820 and ISO 13485. GEHC believes that the extensive bench testing performed are sufficient for FDA's substantial equivalence determination.
Aurora has been independently tested and conforms with IEC 60601-1 and its applicable Collateral and Particular Standards including IEC 60601-1-2, 60601-1-3, 60601-2-44, as well as performance testing per NEMA NU-1.
The following quality assurance measures were applied to the development of the system:
• Risk Analysis
• Required Reviews
• Design Reviews
• Testing on unit level (Module verification)
• Integration testing (System verification)
• Performance testing (Verification)
• Safety testing (Verification)
Page 9
GE Healthcare 510(k) Premarket Notification Submission for Aurora
• Simulated use testing (Validation)
The testing and results did not raise new or different questions of safety and effectiveness than associated with predicate device. GE believes the proposed Aurora is of comparable type and substantially equivalent to our currently marketed system Aurora (K243605).
Summary of Additional Testing
In addition to the verification and validation testing successfully completed as required by GE Healthcare's quality system, additional engineering bench testing and clinical testing were performed to support substantial equivalence, demonstrate performance, and substantiate the product claims.
Bench Testing
The additional engineering bench testing has successfully evaluated the performance of the DL Automatic kidney segmentation algorithm. The testing evaluated 70 planar NM renal studies acquired using GEHC systems from 2 hospitals in the United States and 1 hospital in Europe, serving a diverse patient population that include a range of ethnicities and demographics. The studies encompassed a range of dynamic renal clinical scenarios, detection technologies and collimators, tracers, scan parameters, and patient age. The studies were segregated, and not used in any stage of the algorithm development. The bench testing used the DICE similarity score to compare algorithm generated contours to ground truth (GT) contours, for evaluating performance against pre-defined acceptance criteria. The GT contours were reviewed and confirmed by an experienced Nuclear Medicine physician. The DL Automatic kidney produced an average DICE score above the predefined success criteria.
Clinical Testing
The clinical testing evaluated the same 70 representative clinical exams, which were used in the additional bench testing. The results of the DL Automatic kidney Segmentation were evaluated by three qualified U.S. readers, who assessed the quality of the segmentation using a 4-point Likert scale. The readers evaluation demonstrated that generated segmentation was of acceptable utility, required minimal user interaction and supports the determination of substantial equivalence. All readers attested that the range of clinical cases reviewed in this evaluation provided adequate representation of the standard clinical practice and that the quality of the kidneys' segmentation generated by the algorithm was acceptable.
Substantial Equivalence Conclusion:
The DL Automatic Kidney Segmentation associated with Aurora does not change the Indications for Use or Intended Use from the predicate and represent equivalent, previously cleared technological characteristics, with no changes to the energy type, operating principles, or control mechanisms.
GEHC's quality system's design, verification, and risk management processes did not identify any new hazards, unexpected results, or adverse effects stemming from the changes to the predicate.
Aurora with DL Automatic kidney Segmentation was developed under GE Healthcare's quality system. Design verification, along with bench testing and the clinical reader evaluation included in "Performance Testing" section of this submission, demonstrate that Aurora is substantially equivalent to, and hence as safe and effective for its Intended Use as the legally marketed predicate device.
