    AI/ML Overview

    This document is a 510(k) Premarket Notification for a Magnetic Resonance Diagnostic Device Accessory (MRI system), specifically the EXCELART™ with Pianissimo. The submission is focused on demonstrating substantial equivalence to a predicate device, rather than proving performance against specific acceptance criteria for a novel AI algorithm or diagnostic tool.

    Therefore, many of the requested categories (e.g., sample sizes for test/training sets, ground truth establishment, expert qualifications, MRMC studies, standalone performance) are not applicable or not explicitly detailed in this type of submission for this kind of device. The focus here is on the safety and performance characteristics of the MRI system itself and its accessories.

    Here's a breakdown based on the provided text, indicating what information is available and what is not:


    1. Table of Acceptance Criteria and Reported Device Performance

    For an MRI system, performance is generally evaluated against safety parameters and imaging capabilities rather than diagnostic accuracy metrics. The document specifies safety parameters and imaging volumes.

    Decoupling is dual active and achieved with PIN diodes. The impedance of the coil is 50 ohms nominal and it is a solenoid type coil.

    The Flexible Small Parts coil is constructed with the same materials that are currently in use for the released coil set for OPART™.

    AI/ML Overview

    This request cannot be fulfilled. The document does not contain information about acceptance criteria and device performance for the K991740 submission. It describes a medical device accessory (Flexible Small Parts coil for OPART™ MRI system) and states its intended use, but it does not include performance metrics or a study. The document is primarily a 510(k) summary and the FDA's clearance letter, which focus on substantial equivalence to a predicate device rather than detailed performance studies against specific acceptance criteria.

Signal is received in QD mode when used in conjunction with the T-spine surface coil.
    The Extra Large Body Coil is constructed with the same materials that are currently in use for the released coil set for OPART™.

    AI/ML Overview

    This document describes the design and regulatory approval of an "Extra Large Body Coil" for an MRI system, the OPART™. The information provided primarily focuses on establishing the device's substantial equivalence to a previously cleared device, rather than a clinical study evaluating its performance against specific acceptance criteria in a medical context.

    Based on the provided text, there is no clinical study that explicitly defines and proves the device meets specific performance acceptance criteria in the way typically expected for a diagnostic AI/medical device. Instead, the submission focuses on substantial equivalence for a physical component (the coil) of an MRI system.

    Here's an analysis of the requested information based on the provided text:

    1. Table of Acceptance Criteria and Reported Device Performance

    The concept of "acceptance criteria" for algorithms or diagnostic performance metrics (e.g., sensitivity, specificity, AUC) is not applicable here because this is a hardware accessory submission based on substantial equivalence. The "performance" being evaluated is related to physical and safety parameters of the MRI coil.

    AI/ML Overview

    The provided text is a 510(k) Premarket Notification for the EXCELART Magnetic Resonance Diagnostic Device Accessory (MRI System). This document focuses on demonstrating substantial equivalence to a predicate device, rather than providing independent clinical study results with detailed acceptance criteria and performance metrics for a new, non-inferiority claim.

    Therefore, many of the requested details about acceptance criteria, specific study designs, sample sizes, and expert adjudications are not explicitly stated or applicable in the context of this 510(k) submission.

    Here's an analysis of the provided information relative to your request:

    1. A table of acceptance criteria and the reported device performance

    The submission does not outline specific, quantitative acceptance criteria for image quality or diagnostic accuracy in the way a clinical study for a new AI device would. Instead, it demonstrates that the EXCELART system's safety and imaging performance parameters are comparable to its predicate device, the VISART™/Hyper system.

    AI/ML Overview

    The provided document is a 510(k) Premarket Notification for a diagnostic magnetic resonance device (OPART™ version 2.5/2.6 software for MRT-600) from 1999. It focuses on the safety and imaging performance parameters of the MR system and its software updates. It does not contain information related to a clinical study with acceptance criteria for a device's diagnostic performance, nor does it describe a study involving human readers, ground truth establishment, or multi-reader multi-case analysis as typically seen for AI/CAD devices.

    Therefore, most of the requested information cannot be extracted from the provided text.

    Here is what can be inferred or stated based on the document:

    1. A table of acceptance criteria and the reported device performance

    The document lists "Safety Parameters" and "Imaging Performance Parameters" which function as specifications for the device. These are accepted as meeting the requirements for substantial equivalence.

    Device Description

    The Large and Medium Flexible QD Body coils are essentially a QD (quadrature) extension and a flexible version of the standard Body Coil. The extension consists of adding a saddle trace to the existing solenoid trace. The two independent RF traces have RF magnetic fields which are orthogonal (oriented at 90 degrees with respect to each other) to create a quadrature coil. The NMR signals from the two independent loops are sent to an RF front end where they are then amplified and combined (summed) to provide a resultant signal with improved signal-to-noise ratio. With the coil's flexibility. RF connectors are added which enable the coil to open for patient loading. This enables the coil to be placed directly on the patient pallet. The standard body coil requires the patient to lay on the patient pallet then the patient with pallet is slid through the body coil. An advantage of placing the patient directly on the coil is that the pallet does not go through the coil. Hence the pallet is not filling the coil. This enables the coil to be physically smaller, for improved signal to noise, without losing space for patient loading.

    AI/ML Overview

    The provided document is a 510(k) Premarket Notification for a Magnetic Resonance Diagnostic Device Accessory (OPART™ MRT-600 Large and Medium Flexible QD Body coils).

    This type of submission focuses on demonstrating substantial equivalence to a previously legally marketed device, not necessarily on proving that the device meets specific performance acceptance criteria through a rigorous independent study with defined metrics.

    Therefore, the document does not contain the detailed information requested regarding acceptance criteria, reported device performance, sample sizes for test/training sets, expert qualifications, adjudication methods, MRMC studies, standalone performance studies, or how ground truths were established, as these are typically part of a comprehensive clinical study report, which is not included here.

    Instead, the submission demonstrates "safety and effectiveness" by comparing the new device to a predicate device (Matrix 3000 Flexible Spine Coil, K964753) and stating that the modifications "do not raise new questions of safety or efficacy."

    However, I can extract the safety and imaging performance parameters listed for the device, which might be considered "acceptance criteria" in a general sense for the device's operational characteristics, rather than diagnostic accuracy.

    Here's a summary of what information is available in the provided text, structured to address your request as much as possible:

    1. Table of Acceptance Criteria and Reported Device Performance

    As noted, these are not diagnostic performance metrics, but rather operational specifications. The document implicitly states that the device meets these specifications as part of its design and intended function, making it substantially equivalent to the predicate.
