    Intended Use

    The indication for use for the Transmit/Receive Quadrature Body Coil 3.0T expands the INTERA 3.0T system capability as a diagnostic device that produces transverse, sagittal, coronal and oblique cross-sectional images based upon 'H metabolites, and that displays the internal structure of the whole body. These images when interpreted by a trained physician, yield information that may assist in diagnosis

    Device Description

    The Transmit Receive Quadrature Body Coil 3.0T is a bird-cage type transmit/receive coil designed for use in the Intera 3.0T system. In transmit mode the coil is used in almost every kind of scan. In receive mode the coil is mainly used for imaging with a large field of view. The QBC has a fixed position inside the gradient coil.

    AI/ML Overview

    The provided text describes a 510(k) submission for a medical device, the "Transmit/Receive Quadrature Body Coil 3.0T." This document focuses on demonstrating substantial equivalence to a predicate device, rather than presenting a performance study with acceptance criteria in the typical sense of algorithm-based or diagnostic efficacy studies.

    Therefore, many of the typical acceptance criteria and study details you'd expect for an AI or diagnostic imaging device are not applicable to this submission. The "acceptance criteria" here are primarily regulatory: demonstrating that the new device is as safe and effective as a legally marketed predicate device.

    Here's how to address your request based on the provided text:

    1. Table of Acceptance Criteria and Reported Device Performance

    Acceptance Criteria (Implicit from Substantial Equivalence and Safety)Reported Device Performance (from submission)
    Safety: Device operates safely and does not introduce new hazards."The safety of the INTERA 3.0T system with the Transmit/Receive Quadrature Body Coil 3.0T remain the same as with the FDA cleared INTERA 1.5T (re. K001796)." "The QBC 3.0T does not result in any new potential hazard." Implicitly, the device meets NEMA voluntary standards, FDA MRDD guidance's, UL and IEC 601 appropriate safety standards and/or draft standards (as stated in the General Information section for the product).
    Intended Use Equivalence: Device performs the same functions for the same indications as the predicate."The indication for use for the Transmit/Receive Quadrature Body Coil 3.0T expands the INTERA 3.0T system capability as a diagnostic device that produces transverse, sagittal, coronal and oblique cross-sectional images based upon 'H metabolites, and that displays the internal internal structure of the whole body. These images when interpreted by a trained physician, yield information that may assist in diagnosis." This is an expansion of the system's capability, making the 3.0T system a whole-body scanner, similar to the 1.5T predicate.
    Design/Technological Equivalence: Device design and technology are substantially similar to the predicate."The Transmit Receive Quadrature Body Coil 3.0T is a bird-cage type transmit/receive coil designed for use in the Intera 3.0T system." "The Transmit/Receive Quadrature Body Coil 3.0T is equivalent to Quadrature Body Coil used with the INTERA 1.5T system."

    The "study" proving the device meets these (mostly implicit) acceptance criteria is the substantial equivalence comparison presented in the 510(k) submission itself.

    2. Sample size used for the test set and the data provenance

    • Not Applicable. This is a hardware component submission based on substantial equivalence. There is no test set of patient data or images mentioned for performance evaluation in the context of diagnostic accuracy, as would be expected for an AI or diagnostic tool. The comparison is against an existing hardware component.

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

    • Not Applicable. See point 2. There's no clinical "ground truth" establishment in this type of submission.

    4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

    • Not Applicable. See point 2.

    5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

    • No. This is a hardware component (MRI coil), not an AI device. No MRMC study was conducted or mentioned.

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

    • No. This is a hardware component (MRI coil), not an algorithm.

    7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

    • Not Applicable (in the clinical diagnostic sense). The "ground truth" for this submission is regulatory: the proven safety and effectiveness of the predicate device (the Quadrature Body Coil used with the INTERA 1.5T system), to which the new device is being compared for substantial equivalence.

    8. The sample size for the training set

    • Not Applicable. There is no "training set" as this is not an AI or algorithm-driven device.

    9. How the ground truth for the training set was established

    • Not Applicable. There is no "training set" or corresponding ground truth establishment process.

    In summary:

    This 510(k) submission for the Transmit/Receive Quadrature Body Coil 3.0T is a technical submission focused on demonstrating that a new hardware component built for an existing MR system is substantially equivalent to a previously cleared hardware component for a different MR system from the same manufacturer. The "study" here is the engineering and regulatory comparison of design, materials, and intended use, rather than a clinical performance study involving patient data.
