(Radiology), 2024e - IEC 62304 Edition 1.1 2015 - Medical device software - Software life cycle process - IEC 62366-1: 2015 + A1:2020 – Medical Device-Part 1: Application of Usability. The following quality assurance measures were applied to the development of the system: - Risk Analysis - Requirements Reviews - Design Reviews - Testing on unit level (Module verification) - Integration testing (System verification) - Performance testing (Verification) - Safety testing (Verification) {9} GE HealthCare 510(k) Premarket Notification Submission # AI Auto Doppler Summary of Testing: Summary test statistics and other results including acceptance criteria and information supporting the appropriateness of the characterized performance are provided below. The AI Auto Doppler feature utilizes 2 AI algorithms, Tissue Doppler and Doppler Trace, which are referenced below. ## Testing dataset: - Testing dataset representative of standard clinical practices used to collect typical cardiac images in clinical environments were assessed by experts for accuracy. - Tissue Doppler testing dataset included 4106 recordings from 805 individuals. - Doppler Trace testing dataset included 3390 recordings from 1369 individuals. ## Distribution of testing dataset (Demographics and Ultrasound System): - Gender: Male and Female - Age: Adult and Pediatric - Ethnicity/Country: USA (several locations), Australia, France, Spain, Norway, Italy, Germany, Thailand, Philippines - Ultrasound Console(s): Vivid E80, Vivid E95, Vivid E9, Vivid IQ, Vivid S70, Vivid T9, Vivid Q, Vivid Pioneer - Probe(s): 6Sc, 6Vc, 3Sc, 4Vc, 4V, M5S, 6S, M4S, M5Sc, M5S, 12S, 9VT, 6VT, 10T ## Information about clinical subgroups and confounders present in the testing dataset: - The algorithm performance was verified across a range of confounders: Ethnicity/Country (USA - several locations, Australia, France, Spain, Norway, Italy, Germany, Thailand, Philippines), wide range of Vivid consoles, wide range of probes. ## Performance demonstrated on the verification (testing) dataset: - The verification requirement included a step to check for a feasibility score of more than 95%, as well as an expected accuracy threshold calculated as the mean absolute difference in percentage for each measured parameter. - The verification requirement included a step to check mean percent absolute error across all cardiac cycles against a threshold. All clinical parameters, as performed by AI Cardiac Auto Doppler without user edits passed this check. These results indicate that observed accuracy of each of the individual clinical parameters met the acceptance criteria. - The performance of AI Cardiac Doppler algorithm was evaluated across two BMI groups (<25 and ≥25) using a subset of the Vivid Pioneer dataset containing BMI data (41 patients, 433 Doppler measurements). Manual Doppler measurements, reviewed by clinical experts, served as reference values for assessing the AI results. Performance was evaluated separately for tissue and flow Doppler parameters using a predefined metric quantifying agreement between manual and AI-derived peak velocities. For tissue Doppler, the mean performance metric was -0.002 (SD = 0.077) for BMI < 25 and - Page 6 of 7 {10} Page 7 of 7 GE HealthCare 510(k) Premarket Notification Submission 0.006 (SD = 0.081) for BMI ≥ 25. For flow Doppler, the means were 0.021 (SD = 0.073) and 0.003 (SD = 0.057), respectively. The number of total samples, if different from above, and the relationship between the two: - Tissue Doppler development dataset included 1482 recordings from 4 unique clinical sites (not used for testing dataset). - Doppler Trace development dataset included 2070 recordings from 4 unique clinical sites (not used for testing dataset). Information about equipment and protocols used to collect images: - Development dataset included images obtained with the M5Sc, M5S, 4Vc, 4V, M4S, 6S, 12S, 6Vc, 6VT probes on a variety of Vivid cardiovascular ultrasound systems (Vivid E80, Vivid E95, Vivid E9, Vivid 7, Vivid S70N) Information about how the reference standard was derived from the dataset (i.e. the "truthing" process): Ground truth annotations of the development and verification datasets were obtained as follows: - In all Training, Validation, and Testing datasets, annotators performed manual measurements after assessing Doppler signal quality and ECG signal quality of curated images. - Two cardiologists performed the annotations following US ASE based annotation guidelines. - A review panel of five clinical experts provided feedback on the annotations which were corrected (as needed) until a consensus agreement was achieved between the annotators and reviewers. Description of how independence of test data from training data was ensured: - The testing dataset is selected from independent clinical research institutions that have never been used for training and validation (tuning), ensuring the elimination of potential data leakage. ## Summary of Clinical Tests: The subject of this premarket submission, EchoPAC Software Only / EchoPAC Plug-in, did not require clinical studies to support substantial equivalence. ## Conclusion: Based on the design similarities, conformance to recognized performance standards, and performance testing, GE HealthCare considers the proposed EchoPAC Software Only / EchoPAC Plug-in to be as safe, effective, and performs in a substantially equivalent manner as the predicate EchoPAC Software Only / EchoPAC Plug-in (K220940).
