Device Description

The purpose of this Traditional 510(k) Pre-Market Notification is to introduce the Auto ElastQ software feature onto the EPIQ and Affiniti Series Diagnostic Ultrasound Systems. The proposed EPIQ Series Diagnostic Ultrasound System and Affiniti Series Diagnostic Ultrasound Systems with new Auto ElastQ software feature, which is a workflow-enhancement software feature, is equivalent to predicate device, K240850.

The Auto ElastQ software feature is intended to assist users in making stiffness measurements using 2D-SWE in the liver by recommending specific frames and ROI positions to the user.

No hardware changes to the EPIQ or Affiniti Systems are reguired when using the Auto ElastQ software feature, and existing, commercialized Philips transducers are used for the Auto ElastQ software feature. The feature is supported by EPIQ and Affiniti models running software version 12.0.

AI/ML Overview

Here's a summary of the acceptance criteria and the study conducted for the Philips Auto ElastQ software feature, based on the provided FDA 510(k) summary:

1. Table of Acceptance Criteria and Reported Device Performance

Acceptance Criteria CategoryAcceptance Criteria (Implicit for high agreement)Reported Device Performance
Agreement with Manual Elastography MeasurementsHigh agreement between algorithm-generated measurements and manual measurements.Demonstrated high agreement of Auto ElastQ algorithm-generated measurements with manual elastography measurements based on statistical analysis.

2. Sample Size Used for the Test Set and Data Provenance

  • Test Set Sample Size: Not explicitly stated. The document mentions "a retrospective data analysis study was conducted to evaluate the performance of the Auto ElastQ software compared to manual measurements."
  • Data Provenance: Retrospective data analysis. Country of origin not specified.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications

  • Number of Experts: Not explicitly stated. The ground truth was established by "manual measurements performed by expert readers."
  • Qualifications of Experts: Not explicitly stated beyond "expert readers."

4. Adjudication Method for the Test Set

  • Adjudication Method: Not explicitly stated. The ground truth was established by "manual measurements performed by expert readers," implying an expert consensus or single expert reading for the manual measurements. No information suggestive of a 2+1 or 3+1 method is provided.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

  • MRMC Study: No. This document describes a study comparing the algorithm's performance to expert manual measurements, not a comparative effectiveness study of human readers with and without AI assistance.

6. Standalone (Algorithm Only) Performance Study

  • Standalone Study: Yes. The "retrospective data analysis study" directly evaluated the performance of the Auto ElastQ software (algorithm) "compared to manual measurements performed by expert readers." This indicates a standalone performance assessment of the algorithm.

7. Type of Ground Truth Used

  • Ground Truth Type: Expert consensus/manual measurements. The summary states, "with the manual measurements used as ground truth for the study."

8. Sample Size for the Training Set

  • Training Set Sample Size: Not explicitly stated. The document focuses on the performance study and does not detail the training set size for the AI algorithm.

9. How Ground Truth for the Training Set Was Established

  • Training Set Ground Truth Establishment: Not explicitly stated. The document describes the "Auto ElastQ software feature is intended to assist users in making stiffness measurements using 2D-SWE in the liver by recommending specific frames and ROI positions to the user." While the testing involves expert manual measurements as ground truth, the method for establishing ground truth for the training data used to develop the algorithm is not detailed in this summary.

Dear Chanrasmey White:

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/cfpm/pm.cfm identifies combination product submissions. The general controls 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. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

VI. Safety Considerations

{8}------------------------------------------------

The subject device comply with the referenced standards as well as the FDA ultrasound guidance document. Guidance for Industry and FDA Staff – Marketing Clearance of Diagnostic Ultrasound Systems and Transducers, issued on February 2023.

VII. Non-Clinical Performance Data

The proposed modification of the EPIQ Series and Affiniti Series Diagnostic Ultrasound Systems was tested in accordance with Philips Internal Procedures. The design process incorporated IEC 62304 Medical Device Software - Software life cycle processes, 2006 + A 2015 and Risk Management procedures were applied in accordance with ISO 14971 Medical devices - Application of risk management to medical devices, to ensure the continued safe and effective performance. All software verification tests met the acceptance criteria.

Non-clinical verification testing was conducted to address the change and performance test data were provided to support the introduction of the subject software algorithm for the Auto ElastQ software feature. All software verification tests met the acceptance criteria.

A retrospective data analysis study was conducted to evaluate the performance of the Auto ElastQ software compared to manual measurements performed by expert readers, with the manual measurements used as ground truth for the study. The results demonstrated high agreement of Auto ElastQ algorithm-generated measurements with manual elastography measurements, meeting the acceptance criteria for the study.

VIII. Clinical Data

The proposed EPIQ and Affiniti Series Diagnostic Ultrasound System did not require clinical data for determination of substantial equivalence since substantial equivalence was demonstrated based on the following attributes:

  • Design features ●
  • Indications for use ●
  • Fundamental scientific technology .
  • Non-clinical performance testing ●
  • Safety and effectiveness ●

IX. Conclusion

For testing, all pre-determined acceptance criteria were met. Results of these tests show that the proposed Auto ElastQ software feature meets the intended use. The proposed devices and predicate device:

  • Are indicated for the diagnostic ultrasonic imaging and fluid flow analysis. ●
  • Have identical intended users and use environments. ●
  • . Have the same device classification, product codes.
  • Have identical software. ●
  • Are introducing no new hardware or transducers. ●

The differences between the proposed device and predicate device do not raise new questions of safety and/or effectiveness. The major differences include:

  • The Auto ElastQ feature recommends particular frames that are assessed to be most stable and ROI locations that are assessed to be the most stable and homoqenous to the user, where the predicate devices require users to review a loop of elastography images then uses the trackball to cine to the frames that are visually perceived to be the most stable and manually positions the ROI in a location that appears to be most stable and homogenous.
