The Extra Large Body coil is an enlarged version of the current OPART™ Large Body Coil. This coil is an optional coil which was developed to allow positioning of larger sized patients in the OPART™ system. The Extra Large Body coil can be used as a standalone coil, or in conjunction with the T-spine surface coil (cleared with OPART™ system K962933). 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™.

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.
