The MR Fiber Optic ECG Gating System is intended to be used when it is necessary to svnchronize the MR scanner's data acquisition with the patient's electrocardiogram.

The MR Fiber Optic ECG Gating System measures and digitizes the patient's electrocardiogram, detects the presence of an R-wave and provides a trigger to the Signa MR system. The gating system provides for operator control of parameters used in the R-wave detection algorithms and control of gate delay. The electrocardiogram waveform is displayed along with the gate, heart rate and the measured R to R interval.

The provided text describes the MR Fiber Optic ECG Gating System. However, it does not contain specific acceptance criteria or a detailed study description with performance metrics in the way you've outlined.

The document primarily focuses on regulatory approval (510(k) submission) and states that performance testing was conducted to demonstrate substantial equivalence to a predicate device.

Here's an analysis based on the available information, highlighting what is not present as per your request:

1. Table of Acceptance Criteria and Reported Device Performance

Missing Information:

• Specific numerical targets for performance metrics (e.g., accuracy of R-wave detection, latency, heart rate measurement accuracy, synchronization stability).
• Quantitative results from operating in the MRI environment.

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

• Sample Size: Not specified.
• Data Provenance: Not specified (e.g., country of origin, retrospective or prospective).

3. Number of Experts Used to Establish Ground Truth and Qualifications

• Number of Experts: Not specified.
• Qualifications of Experts: Not specified.

4. Adjudication Method for the Test Set

• Not specified.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

• Was it done?: No mention of an MRMC study. The comparison was to a predicate device (Gating cable provided by General Electric), not explicitly human readers.
• Effect size of human readers with vs. without AI assistance: Not applicable, as no MRMC or human-AI comparison is described.

6. Standalone Performance Study

• Was it done?: Yes, to some extent. The document states "tests were performed to establish that the Gating system operated in the MRI environment substantially equivalent to the predicate device." This implies a standalone evaluation of the device's function. However, detailed performance metrics are not provided.

7. Type of Ground Truth Used

• Given the nature of an ECG gating system, the ground truth would likely be established through:
  • Reference ECG measurements: Gold standard ECG readings.
  • Simulated physiological signals: Controlled inputs to test R-wave detection and timing.
  • Comparison to predicate device's output: As mentioned, substantial equivalence to the predicate device was evaluated, implying the predicate's performance served as a benchmark for "ground truth" or acceptable performance in the MRI environment.

Missing Information: The specific method of ground truth establishment is not detailed.

8. Sample Size for the Training Set

• Sample Size: Not specified. The document does not mention any "training set" in the context of machine learning or AI. This device appears to be a hardware/firmware system for signal detection and gating, not an AI-driven image analysis tool that would typically involve a "training set."

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

• Not applicable, as a training set for machine learning is not mentioned.

In summary: The provided document is a 510(k) summary, which is typically a high-level overview focused on regulatory compliance and substantial equivalence. It does not contain the detailed, quantitative performance study data or methodology that would be present in a scientific publication or a more comprehensive technical report. The "performance testing" mentioned is general and refers to compliance with international standards and substantial equivalence to a predicate device.
