Modes of operation include: B Mode, M Mode, PW Doppler, CW Doppler, Color Doppler, Color M Mode, Power Doppler, and Harmonic Imaging.
The clinical environments where the Affiniti Diagnostic Ultrasound Systems can be used include Clinics, Hospitals, and clinical point-of-care for diagnosis of patients.
The systems are intended to be installed, used, and operated only in accordance with the safety procedures and operating instructions given in the product user information. Systems are to be operated only by appropriately trained healthcare professionals for the purposes for which they were designed. However, nothing stated in the user information reduces your responsibility for sound clinical judgment and best clinical procedure.
The purpose of this Special 510(k) Pre-Market Notification is to expand the Smart View Select (SVS) software application onto the Affiniti Series Diagnostic Ultrasound Systems and to modify the Smart View Select software application onto both the EPIQ Series Diagnostic Ultrasound Systems.
Smart View Select is an automated software feature that assists the user in selection of images for analysis with the existing Philips AutoStrain LV or 2D Auto LV application in Adult Echo Transthoracic (TTE) examination. This feature automatically classifies each acquired image by view and selects an appropriate set of images for left ventricle (LV) analysis. The classification is based on a Deep Learning AI interface engine; the selection is a non-AI algorithm that considers the view classification and image depth to select the optimal set of images.
No hardware changes to the EPIQ or Affiniti systems are required when using SVS, and existing, cleared Philips TTE transducers are used with these software applications.
The SVS v2 feature is supported by all EPIQ models running software version 13.0 or higher including EPIQ CVx/CVxi, EPIQ Elite Advanced, EPIQ Elite, EPIQ 7, EPIQ 5. The SVS v2 feature is supported by the Affiniti models running software version VM13.0 or higher, including Affiniti CVx, Affiniti 70, Affiniti 50, and Affiniti 30. The SVS and SWM software features are associated with the cardiac adult indication.
The provided document details the 510(k) clearance for Philips Ultrasound's EPIQ and Affiniti Series Diagnostic Ultrasound Systems with the Smart View Select (SVS) v2 software. The SVS feature is an automated software that assists users in selecting images for Left Ventricle (LV) analysis using existing Philips AutoStrain LV or 2D Auto LV applications in Adult Echo Transthoracic (TTE) examinations. It classifies acquired images by view using a Deep Learning AI interface and then uses a non-AI algorithm to select an optimal set of images.
Here's an analysis of the acceptance criteria and the study that proves the device meets them:
1. Table of Acceptance Criteria and Reported Device Performance
The study aimed to demonstrate agreement between LV analysis outputs (Ejection Fraction - EF, and Global Longitudinal Strain - GLS) derived from manually selected clips (ground truth) and automatically selected clips by the SVS software.
| Acceptance Criteria | Reported Device Performance |
|---|---|
| Co-primary Endpoint: Lower Confidence Bound for Pearson's correlation coefficient to be > 0.8 for both GLS and EF measurements. | Pearson's Correlation Coefficient for EF: 0.891 (95% CI: 0.851, 0.920) Lower Confidence Bound: 0.851 (Met criteria) |
| Pearson's Correlation Coefficient for GLS: 0.906 (95% CI: 0.871, 0.931) Lower Confidence Bound: 0.871 (Met criteria) |
2. Sample Size and Data Provenance
- Test Set Sample Size: The exact number of patients or cases in the test set is not explicitly stated as a single number. However, the demographic characteristics section indicates
n=71for various demographic variables like Sex, Age, Height, Weight, BMI, Race, LV systolic function, RWMA, Known CAD, Previous reported MI Location, and LV Hypertrophy, suggesting the test dataset comprised data from at least 71 unique patients. - Data Provenance: The data was collected from a US-based medical center. The study was a retrospective data analysis.
3. Number of Experts and Qualifications for Ground Truth
- Number of Experts: Three (3) reviewers (clinical experts) participated in establishing the ground truth.
- Qualifications of Experts: They are referred to as "clinical experts." No further specific qualifications (e.g., years of experience, specific board certifications like radiologist/cardiologist) are provided in the document.
4. Adjudication Method for the Test Set
The adjudication method used to establish ground truth was consensus/averaging. For each output (GLS and EF), the average across the three reviewers was used as the ground truth.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
No Multi-Reader Multi-Case (MRMC) comparative effectiveness study was described. The study focused on comparing the AI-selected clips' performance (GLS and EF) against the ground truth established by human experts using manually selected clips. There is no information provided regarding how much human readers improve with AI vs. without AI assistance. The study evaluates the AI's ability to select optimal clips, a step that precedes human analysis with AutoStrain LV.
6. Standalone Performance Study (Algorithm Only)
Yes, a standalone performance study was done. The performance of the SVS software was evaluated solely based on its ability to automatically select appropriate clips, and then the subsequent, un-edited evaluation of GLS and EF through AutoStrain LV using these SVS-selected clips was compared against the human-selected clips. This represents the algorithm's performance in its specific task (clip selection) without direct human intervention in the selection process.
7. Type of Ground Truth Used
The ground truth used was expert consensus. Specifically, it was the average of GLS and EF measurements obtained from clips manually selected and subsequently semi-automatically processed by three clinical experts using the AutoStrain LV software.
8. Sample Size for the Training Set
The document does not provide the sample size used for the training set of the deep learning AI model for image classification. It only states that "the neural network of the subject device was revised as described in attachment 002," implying updates to an existing model rather than a completely new one, but no training data details are given.
9. How Ground Truth for Training Set was Established
The document does not explicitly state how the ground truth for the training set was established. It mentions that the "classification is based on a Deep Learning AI interface engine," but details regarding the training data annotation and ground truth establishment are not provided within the excerpt.

| Application Description | Smart View Select is an automated software feature that assists you in the selection of images for analysis with the existing Philips AutoStrain LV or 2D Auto LV application in Adult Echo Transthoracic examination. This feature automatically classifies each acquired image by view and selects an appropriate set of images for Left ventricle (LV) analysis. The classification is based on a Deep Learning AI interface engine; the selection is a non-AI algorithm that considers the view classification and image depth to select the optimal set of images.You can launch AutoStrain LV or 2D Auto LV with the set of images that have been automatically selected without the need to review the acquired images and manually select the views. | Smart View Select is an automated software feature that assists you in the selection of images for analysis with the existing Philips AutoStrain LV or 2D Auto LV application in Adult Echo Transthoracic examination.

VI. Safety Considerations
The proposed EPIQ and Affiniti Series Diagnostic Ultrasound Systems, including SVS v2 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 and Affiniti Series Diagnostic Ultrasound Systems 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
- IEC 62366-1 Medical devices - Part 1: Application of usability engineering to medical devices Edition 1.1 2020-06 CONSOLIDATED VERSION
- 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 SVS v2 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
In addition, a retrospective data analysis studies were performed to support the substantial equivalence of the SVS v2 features integrated onto EPIQ and Affiniti:
The study was conducted to evaluate the performance of the SVS workflow enhancement algorithm. Three reviewers (clinical experts) participated in the manual selection of clips from subject exam and subsequent semi-automated processing of the clips with AutoStrain LV software to evaluate GLS and EF, which served as ground truth (average across reviewers for each output). The same exams were processed through the SVS software for automatic selection of appropriate clips and subsequent, un-edited evaluation of GLS and EF with AutoStrain LV. GLS and bi-plane EF results for each subject evaluated by the reviewers (averaged across reviewers= ground truth) were compared to the automatically obtained GLS and EF results with SVS selected clips.
The co-primary endpoints for the study were defined as agreements between GLS/EF measured via manual clip selection and compared to SVS clip selection and GLS/EF output using AutoStrain LV software. Agreement was measured as correlation for each output, separately for GLS and EF (co-primary endpoints). A review of the published literature and previous regulatory submissions (K130779, K232500) informed the acceptance criteria for the study to be defined as Lower Confidence Bound for the Pearson's correlation coefficient to be >0.8. In addition to Pearson's correlation assessment, Bland-Altman analysis was performed for EF and GLS
Demographic characteristics data were available from a subset of the study population. The demographic characteristics for this subset of the study population are presented below in the table below.

The results of the primary endpoints analysis demonstrate acceptable performance for automatic selection of appropriate clips by SVS software and subsequent output of GLS and EF with AutoStrain LV compared to the results published in literature for EF and GLS. Specifically, for the Pearsons' correlation coefficient was 0.891 (95%CI 0.851, 0.920) for the EF and 0.906 (95%CI 0.871, 0.931) for the GLS measurement. The lower confidence bounds were 0.871 for GLS and 0.851 for EF, thereby meeting the predefined acceptance criteria for the study. Taken together, success of the primary endpoint and supporting additional analyses indicate that the safety and effectiveness of the proposed subject software, SVS, is acceptable and aligns with the previously reported performance.
Since this is a software-only change and no new hardware was added, no acoustic output, cleaning and disinfectant, thermal, electrical, electromagnetic, and mechanical safety testing were required. Biocompatibility testing is not needed for the subject EPIQ and Affiniti Series Diagnostic Ultrasound Systems with SVS v2. The transducer patient contact materials and manufacturing processes are not impacted by the release of the subject EPIQ and Affiniti Series Diagnostic Ultrasound Systems with SVS v2.
VIII. Clinical Data
There was no clinical investigation needed for this premarket submission of the EPIQ and Affiniti Series Diagnostic Ultrasound Systems with SVS v2 software applications.
IX. Sterilization
Not applicable. The ultrasound transducers are not supplied sterile.
X. Conclusion
For testing, all pre-determined acceptance criteria were met. Results of these tests 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.
