This submission consists of a new Magnetic Resonance Imaging system which is based primarily on the cleared EXCELARTTM (K990620) with the following new functions added to the standard system. • Pianissimo: Gradient acoustic reduction system • QD Whole Body coil • QD Head coil • QD C/T/L Spine Array coil • 18.1" LCD flat screen monitor • Increase of SAR limit from

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.

Versions v3.0/v3.1/v3.2/v3.3 software are a combination of modifications and the addition of new sequences to the existing software, which facilitate the acquisition and reconstruction of MR images. The four versions have the same base software features with certain additional features available in each subsequent version (see Comparison Table, Appendix B, for detailed description). A brief description follows: - v3.0: Based on v2.5 (K990260) with MR Angio and FASE sequences removed - v3.1: Based on v2.5 (K990260) - v3.2: Based on v2.6 (K990260) - v3.3: Based on v2.6 (K990260) with addition of Perfusion/Diffusion imaging

This 510(k) premarket notification describes an upgrade to an existing Magnetic Resonance Diagnostic Device, the OPART™ (Model MRT-600), to software versions v3.0, v3.1, v3.2, and v3.3, along with optional hardware items. The core of this submission is to demonstrate substantial equivalence to previously cleared versions and to justify new functionalities and increased safety parameters.

Here's an analysis based on the provided document:

1. Table of Acceptance Criteria and Reported Device Performance

The submission focuses on safety parameters and imaging performance. The "acceptance criteria" appear to be specified maximums for safety and a general "specification volume" for imaging. The "reported device performance" is essentially that the device operates within these stated limits and produces sample images.

This submission consists of a new Magnetic Resonance Imaging system which is based primarily on the cleared VISART™/Hyper system (K965068) with modifications including a short bore magnet and gantry design. The software used with the EXCELART MRI system is V4 (K983110). All other technology used for the EXCELART system is the same as that of the cleared VISART™/Hyper system.

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.
