    AI/ML Overview

    Here's a summary of the acceptance criteria and the study details for the SAMSUNG MEDISON CO., LTD. HERA W9/HERA W10 Diagnostic Ultrasound System, specifically focusing on the AI-based features mentioned in the document:

    1. Table of Acceptance Criteria and Reported Device Performance

    The provided document does not explicitly list quantitative acceptance criteria for the AI-based features. Instead, it states that "Performance testing was successfully completed for the new software functions (artificial intelligence based features HeartAssist, ViewAssist and Slice A) to show passing results for predefined testing criteria," and that for BiometryAssist, "measurement accuracy requirements were met."

    Therefore, based on the provided text, the table would look like this:

    Acceptance Criteria CategorySpecific Acceptance Criteria (as implied)Reported Device Performance
    HeartAssistMeeting "predefined testing criteria" for classification of ultrasound images into measurement views, caliper placement, and measurement results."Performance testing was successfully completed... to show passing results for predefined testing criteria."
    ViewAssistMeeting "predefined testing criteria" for classification of ultrasound images into key scanning views and providing annotations."Performance testing was successfully completed... to show passing results for predefined testing criteria."
    Slice AMeeting "predefined testing criteria" for functionality similar to VCIA."Performance testing was successfully completed... to show passing results for predefined testing criteria."
    BiometryAssist (AI version)Meeting "measurement accuracy requirements" for automatic biometric measurement of fetal growth parameters."validated through performance testing to confirm the measurement accuracy requirements were met."

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

    The document does not provide details on:

    • The specific sample size used for the test set for any of the AI features.
    • The data provenance (e.g., country of origin of the data, retrospective or prospective) for the test set.

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

    The document does not provide details on:

    • The number of experts used to establish the ground truth for the test set.
    • The qualifications of those experts.

    4. Adjudication Method for the Test Set

    The document does not specify any adjudication method used for the test set. It mentions that clinical studies were not required for substantial equivalence and focuses on performance testing.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done

    The document does not indicate that an MRMC comparative effectiveness study was done. It focuses on the performance of the AI features themselves rather than comparing human reader performance with and without AI assistance. The text explicitly states: "The subject of this premarket submission, HERA W9/ HERA W10, did not require clinical studies to support substantial equivalence."

    6. If a Standalone (algorithm only without human-in-the-loop performance) was done

    Yes, the descriptions of HeartAssist, ViewAssist, Slice A, and BiometryAssist (AI version) focus on their automated capabilities ("classification," "proposes caliper placements," "proposes corresponding anatomy annotations," "automatic technology for biometric measurement"). While it mentions user editing, the performance testing appears to validate the algorithm's standalone capabilities against "predefined testing criteria" and "measurement accuracy requirements."

    7. The Type of Ground Truth Used

    The document states that BiometryAssist's accuracy requirements were met for "biometric measurement," implying that quantitative measurement values (likely manually obtained or from established references) were used as ground truth. For HeartAssist, ViewAssist, and Slice A, the ground truth would likely involve expert-defined "measurement views," "key scanning views," and "anatomy annotations," respectively, but the precise nature (e.g., expert consensus) is not detailed.

    8. The Sample Size for the Training Set

    The document does not provide details on the sample size used for the training set for any of the AI features.

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

    The document does not provide details on how the ground truth for the training set was established. It only generally refers to these features as "deep learning based functions" which implies a training process with labeled data.

Its function is to acquire ultrasound dasta and to display the data as B-mode, M-mode, Pulsed wave (PW) Doppler, Continuous wave (CW) Doppler, Color Doppler, Tissue Doppler Imaging (TDI), Tissue Doppler Wave (TDW), Power Amplitude Doppler, Pulse Inversion Harmonic Imaging (S-Harmonic), Directional Power Doppler (S-Flow), Color M-Mode, 3D Imaging Mode, 4D Imaging Mode, Elastoscan+ Mode, Tissue Harmonic Imaging, MV-Flow Mode or as a combination of these modes.

    The HERA W9/HERA W10 also give the operator the ability to measure anatomical structures and offers analysis packages that provide information that is used to make a diagnosis by competent health care professionals. The HERA W9/HERA W10 have real time acoustic output display with two basic indices, a mechanical index and a thermal index, which are both automatically displayed.

    As compared with predicate device(HERA W10, K182595), the subject device has added new three transducers(EV2-10A, EA2-11AV and EA2-11AR) and nine biopsy kits (BP-KIT-079, BP-KIT-080, BP-KIT-081, BP-KIT-082, BP-KIT-085, BP-KIT-086, BP-KIT-089 and BP-KIT-089 and BP-KIT-090) and the product name of HERA W9. There are no change and new software features from the predicate device. The HERA ultrasound system is supported by software and the software is not modified for the subject system.

    AI/ML Overview

    The provided FDA 510(k) summary for the HERA W9/HERA W10 Diagnostic Ultrasound System does not contain information about acceptance criteria or a study proving that the device meets such criteria.

    This is because the submission is for a 510(k) pathway, specifically claiming substantial equivalence to a predicate device (HERA W10, K182595). In such cases, the primary goal is to demonstrate that the new device is as safe and effective as a legally marketed predicate device, rather than proving performance against specific acceptance criteria for a novel technology.

    The document explicitly states:
    "The subject of this premarket submission, HERA W9/ HERA W10, did not require clinical studies to support substantial equivalence."

    Instead, the submission focuses on demonstrating:

    • Technological equivalence: "The HERA W9/ HERA W10 employ the same fundamental scientific technology as its predicate device."
    • Feature similarity: A detailed table comparing features, clinical applications, scanhead types, modes of operation, etc., between the new device and the predicate. The differences noted are primarily hardware variations (DVD, caster size, monitor size, active probe ports) and the addition of new transducers and biopsy kits. Critically, it states, "There are no change and new software features from the predicate device. The HERA ultrasound system is supported by software and the software is not modified for the subject system."
    • Compliance with safety standards: The document lists several IEC, ISO, and NEMA standards that the device conforms to for acoustic output, biocompatibility, cleaning/disinfection, thermal, electromagnetic, and mechanical safety.

    Therefore, since no clinical study was required or performed to prove specific performance metrics against acceptance criteria for the new device itself, I cannot provide the requested information. The device's "performance" is implicitly deemed equivalent to the predicate device through the demonstration of similar technology, intended use, and safety characteristics.

    AI/ML Overview

    I am sorry, but the provided text does not contain sufficient information to answer your request. The document is a 510(k) summary for the HERA W10 Diagnostic Ultrasound System, which primarily focuses on establishing substantial equivalence to predicate devices and detailing the device's intended uses and compliance with safety standards.

    Specifically, the text does not include:

    • A table of acceptance criteria and reported device performance.
    • Details about sample sizes used for test sets, data provenance, number or qualifications of experts for ground truth, or adjudication methods for test sets.
    • Information about a multi-reader multi-case (MRMC) comparative effectiveness study or its effect size.
    • Information about a standalone (algorithm only) performance study.
    • The type of ground truth used (expert consensus, pathology, outcomes data, etc.).
    • The sample size for the training set or how its ground truth was established.

    In fact, section 11 explicitly states: "The subject of this premarket submission, HERA W10, did not require clinical studies to support substantial equivalence." This indicates that detailed performance studies as you've requested were not part of this specific FDA submission.
