Device Description

The purpose of this Traditional 510(k) Pre-Market Notification is to introduce the change in AutoMeasure V3 software application onto the EPIQ Series Diagnostic Ultrasound Systems and Affiniti Series Diagnostic Ultrasound Systems. Philips AutoMeasure feature provides the end user semi-automated 2D, Doppler and M-mode measurements with an adult cardiology transthoracic transducer and acquisitions that includes an electrocardiogram (ECG). The Auto Measure feature is designed to provide semi-automated and editable measures during an echocardiography. When Auto Measure is enabled, the healthcare professional performs an echocardiography with a workflow that provides the user with a semiautomated measurement that can be edited, accepted, or rejected. AutoMeasure is available in the Adult Echo analysis applications with ECG. Availability is also controlled by transducer and preset via the EPM. The software applications are supported by all EPIQ and Affiniti models running software version 13.0 or higher.

AI/ML Overview

Here's an analysis of the acceptance criteria and study proving the device meets those criteria, based on the provided FDA 510(k) summary for Philips AutoMeasure V3 software.

Overview of the Device and Study:
The Philips AutoMeasure V3 software is an optional feature for EPIQ and Affiniti Series Diagnostic Ultrasound Systems. It provides semi-automated 2D, Doppler, and M-mode measurements during adult transthoracic echocardiography (TTE) using an AI-algorithm trained via machine learning. The study aimed to evaluate the performance of AutoMeasure V3 compared to standard of care (SOC) measurements.


1. Table of Acceptance Criteria and Reported Device Performance

The document doesn't explicitly list a table of acceptance criteria in numerical ranges for specific performance metrics (e.g., "accuracy > X%"). Instead, it describes a general acceptance methodology:

Acceptance Criteria for AutoMeasure V3 Software:
"meeting the pre-defined acceptance criteria for the study. Taken together, the results of the study demonstrated clinically reasonable, relevant and meaningful performance of the AutoMeasure V3 software supporting automation of measurements during cardiac TTE exams. Specifically, success on the hypotheses testing for AutoMeasure V3 agreement with ground truth measurements indicate that the safety and effectiveness of the proposed software is acceptable and aligns with previously reported agreement for cardiac assessment. Since the acceptance criteria were based on inter-observer data for echocardiographic measurements, the AutoMeasure V3 performance supports the conclusion that the algorithm behaves like any average human observer. Therefore, the clinical acceptability of AutoMeasure V3 is met."

This implies that the acceptance criteria for each of the 32 tested hypotheses were based on achieving agreement within the confidence intervals typically observed between human observers for echocardiographic measurements. The specific numerical thresholds for these confidence intervals are not provided in the summary.

Reported Device Performance:
The study concluded: "The results of the 32 hypotheses tested, demonstrated high agreement of AutoMeasure V3 software with Standard of Care Measurements (ground truth) obtained during initial subject exam, by producing confidence intervals for the limits of agreement, for each parameter (hypothesis) tested, meeting the pre-defined acceptance criteria for the study."

This indicates that for all 32 tested parameters, the AutoMeasure V3's performance was within the pre-defined limits of agreement, deemed comparable to human inter-observer variability.


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

  • Test Set Sample Size: 7127 transthoracic echocardiography (TTE) cardiac clips from 3964 subjects.
  • Data Provenance: Retrospective, multi-institutional.
    • Country of Origin: USA, Asia, and Europe.
    • Retrospective/Prospective: "Subjects were enrolled at institutions between 2015 and June 2024, and the timeframes varied for different hospitals." This indicates retrospective data collection from existing patient records/imaging archives.
    • Nature of Data: "Patients referred for clinical TTE as well as healthy volunteers were invited to participate."

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

  • Number of Experts: Not explicitly stated as a specific number of unique experts who reviewed the test set for adjudication. The document states "Standard of Care (SOC) measurements obtained during initial subject visit, performed by qualified healthcare professional(s)." This implies that the ground truth was established by the original healthcare professional(s) performing the TTE exam in clinical practice.
  • Qualifications of Experts: "qualified healthcare professional(s)". Specific qualifications (e.g., radiologist, cardiologist, sonographer, years of experience) are not detailed beyond "qualified". Given the context of echocardiography, these would likely be sonographers or cardiologists.

4. Adjudication Method for the Test Set

  • Adjudication Method: Not explicitly described. The ground truth was based on "Standard of Care (SOC) measurements obtained during initial subject visit." This suggests a single reader paradigm where the initial clinical measurement serves as the ground truth, rather than a multi-reader consensus process specifically for the study.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

  • MRMC Study: No, a traditional MRMC comparative effectiveness study where multiple human readers systematically re-read cases with and without AI assistance was not explicitly described. The study focused on the agreement between the AI's measurements and existing Standard of Care human measurements.
  • Effect Size of Human Improvement with AI Assistance: Not applicable, as this type of MRMC study was not performed. The study aimed to show that the AI's measurements were comparable to typical human variability.

6. If a Standalone (Algorithm Only) Performance Study Was Done

  • Standalone Performance: Yes, implicitly. The "Performance Validation Study" evaluated "the performance of the AutoMeasure V3 software... compared to ground truth." While the user can edit the semi-automated measurements, the study's focus on "agreement of AutoMeasure V3 software with Standard of Care Measurements" suggests an evaluation of the algorithm's initial output before human intervention, establishing its standalone capability. The document states, "AutoMeasure V3 is created semi-automatically using machine learning algorithm without user interaction."

7. The Type of Ground Truth Used

  • Type of Ground Truth: Expert consensus (implicitly, as SOC measurements by "qualified healthcare professional(s)"). More specifically, it is "Standard of Care (SOC) measurements obtained during initial subject visit". This suggests reliance on clinical practice measurements rather than a separate, dedicated "gold standard" panel review or pathological confirmation.

8. The Sample Size for the Training Set

  • Training Set Sample Size: Not explicitly stated in this 510(k) summary. The document mentions "training via machine-learning techniques" but does not give the size of the dataset used for this training.

9. How the Ground Truth for the Training Set Was Established

  • Training Set Ground Truth Establishment: Not explicitly stated in this 510(k) summary. However, it's highly probable that the training data's ground truth was also established by human expert annotation or existing clinical measurements, similar to how the test set ground truth was derived.

VI. Safety Considerations

The proposed EPIQ Series Diagnostic Ultrasound System and Affiniti Series Diagnostic Ultrasound System, including AutoMeasure V3 software applications, and compatible transducers are all Track 3 Devices and 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 in February 2023.

VII. Nonclinical Performance Data

The proposed modification of the EPIQ Series Diagnostic Ultrasound System and Affiniti Series Diagnostic Ultrasound was tested in accordance with Philips internal procedures. Philips Ultrasound tested the subject devices per the following standards to ensure the continued safe and effective performance:

  • . IEC 62304 Medical device software - Software life cycle processes, 2006 + A 2015
  • . ISO 14971 Medical devices- Application of risk management to medical devices, 2019

Non-clinical verification testing was conducted to address the change and performance test data were provided to support the introduction of the subject AutoMeasureV3 software applications. The activities to assure the safe and effective performance of the software revision included, but are not limited to, the following:

  • . Requirements Review
  • Risk Analysis and Management Review
  • . Product Specification Review
  • Design Reviews

Non-clinical testing also included the Performance Validation Study for the proposed AutoMeasure V3 software applications.

This study evaluated the performance of AutoMeasure V3 software in automation of measurement from cardiac TTE clips across a diverse set of subject demographics, body habitus and parameters' distribution. Adult subjects (18 years of age and above) from whom the study data were sampled were enrolled in hospital settings at multiple institutions, including USA, Asia and Europe. Subjects were enrolled at institutions between 2015 and June 2024, and the timeframes varied for different hospitals. Patients referred for clinical TTE as well as healthy volunteers were invited to participate. Data independence was ensured by adhering to Philips procedure related to consistent data handling and project documentation independent of the data scientist. The study evaluated the performance of the AutoMeasure V3 software, where 7127 transthoracic echocardiography (TTE) cardiac clips from 3964 subjects were used for assessment of AutoMeasure V3 parameters (measurements) and compared to ground truth. The ground truth for the study was defined as Standard of Care (SOC) measurements obtained during initial subject visit, performed by qualified healthcare professional(s).

The subjects whose TTE clips were used in the study were:

{15}------------------------------------------------

Asian2.70% (107/3964)
Black or African American45.18% (1791/3964)
White30.25% (1199/3964)
Other/Mixed21.85% (866/3964)
Unknown0.03% (1/3964)
BMI (kg/ m²)28.85±7.06 (3964);(12.40;63.60)

In addition, the performance of the software was accessed in analysis stratified by demographic variables (aqe, BMI, gender and race) and clinical status (healthy, suspected of disease).

The results of the 32 hypotheses tested, demonstrated high agreement of AutoMeasure V3 software with Standard of Care Measurements (ground truth) obtained during initial subject exam, by producing confidence intervals for the limits of agreement, for each parameter (hypothesis) tested, meeting the pre-defined acceptance criteria for the study.

Taken together, the results of the study demonstrated clinically reasonable, relevant and meaningful performance of the AutoMeasure V3 software supporting automation of measurements during cardiac TTE exams. Specifically, success on the hypotheses testing for AutoMeasure V3 agreement with ground truth measurements indicate that the safety and effectiveness of the proposed software is acceptable and aligns with previously reported agreement for cardiac assessment. Since the acceptance criteria were based on inter-observer data for echocardiographic measurements, the AutoMeasure V3 performance supports the conclusion that the algorithm behaves like any average human observer. Therefore, the clinical acceptability of AutoMeasure V3 is met. Lastly, the AutoMeasure V3 software is a semi-automated quantitative imaging algorithm, and users are generally expected to review and concur with the initialization and generated results. The users can also edit alqorithm generated measurements and outputs based on their clinical expertise.

Since this is a software-only change and no new hardware was added, no acoustic output, cleaning and disinfectants, thermal, electromagnetic, and mechanical safety testing were required. Biocompatibility testing is not needed for the subject EPIQ Series Diagnostic Ultrasound Systems and Affiniti Series Diagnostic Ultrasound with AutoMeasure V3. The transducer patient contact materials and manufacturing processes are not impacted by the release of the subject EPIQ Series Diagnostic Ultrasound System and Affiniti Series Diagnostic Ultrasound with AutoMeasure V3.

Clinical Data VIII.

There was no clinical investigation needed for this premarket submission of the EPIQ Series Diagnostic Ultrasound Systems and Affiniti Series Diagnostic Ultrasound Systems with AutoMeasure V3 software applications.

IX. Sterilization

Not applicable. The ultrasound transducers are not supplied sterile.

X. Conclusion

Results of the testing show that the proposed subject device meets its intended use support a determination that the proposed subject device does not raise new questions of safety or effectiveness.

Therefore, the subject device is substantially equivalent to the predicate device in terms of indications for use, design, technological characteristics, modes of operations, safety, and effectiveness.
