• Safety: Compliance with relevant safety standards.
• Reliability: Demonstrating reliable operation.
• Substantial Equivalence: Being as safe and effective as the predicate devices.

Since no specific quantitative metrics are provided for the acceptance criteria, a table directly comparing them to reported device performance cannot be created with numerical values. The text only states that the device "meets all design requirements and performance claims."

1. Table of Acceptance Criteria and Reported Device Performance

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

• Sample Size: The document does not specify a patient sample size for any clinical testing. It mentions "Testing on unit level, system level, as well as usability and safety parameters."
• Data Provenance: The document does not mention the country of origin of any data or whether it was retrospective or prospective. The study detailed appears to be a simulated use setting for verification testing rather than a clinical trial on patient data.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications

• The document does not mention the use of experts to establish ground truth for a test set related to interpretation or diagnosis. The testing described focuses on engineering verification, not clinical validation based on expert review.

4. Adjudication Method for the Test Set

• Since there's no mention of expert review or clinical ground truth establishment, no adjudication method (like 2+1 or 3+1) is described.

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

• No, an MRMC comparative effectiveness study was not done. The document explicitly states: "The subject of this premarket submission, MAC™ 2000 ECG analysis system, did not require clinical studies to support substantial equivalence." This means there was no study comparing human readers with and without AI assistance to measure an effect size.

6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study

• The document refers to the "MACTM 2000 ECG Analysis System" as a device that "aquires, analyzes, displays, and records information." The analysis component is embedded in the device. The "Summary of Non-Clinical Tests" and "Summary of Simulated Use Setting" focus on "Design verification... several protocols that include electrical, mechanical, safety testing, reliability, and system design verification." This suggests testing of the integrated system and its analytical capabilities in a controlled engineering environment. However, it does not detail a standalone algorithm performance study in terms of diagnostic accuracy or specific metrics for its "interpretive analysis" option. The focus is on the device's overall functionality and safety, and its equivalence to predicate devices, rather than the isolated performance of its analytical algorithms against a clinical ground truth.

7. Type of Ground Truth Used

• For the described verification testing, the "ground truth" was effectively design requirements and established performance claims, as well as compliance with voluntary standards. There is no mention of clinical ground truth such as pathology, expert consensus, or outcomes data used for the "analysis system" part of the device. The verification focused on whether the device functions as designed and meets engineering specifications and regulatory standards.

8. Sample Size for the Training Set

• The document does not mention any training set size because it did not involve the development or validation of a new AI model with a training phase detailed in this submission. The device uses "the same fundamental technology as its predicate device MAC1600 ECG Analysis System" for acquiring, analyzing, recording, displaying, and printing ECG data. This suggests reliance on established algorithms, rather than newly trained ones requiring a dedicated training set as described in modern AI/ML submissions.

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

• As no training set is mentioned in the context of this submission, the document does not provide information on how ground truth was established for a training set.

Acceptance Criteria and Device Performance

Study Information:

1. Sample size used for the test set and the data provenance:

   • Test Set Sample Size: Not explicitly stated as a numerical count of patients or images. The text mentions "sample clinical images" were obtained.
   • Data Provenance: The study involved "Internal scans within GE Healthcare facility." This indicates the data was likely prospective and collected specifically for this filing. The country of origin is implicitly India ("Wipro GE Healthcare Pvt Ltd, Bangalore, INDIA").

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

   • This information is not provided in the document. The filing focuses on technical and safety equivalence, with clinical images used internally for verification rather than a formal clinical trial with expert interpretation for ground truth.

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

   • This information is not provided. Given the nature of the "internal scans" for "sample clinical images" and the absence of explicit expert review processes, it's highly probable that a formal adjudication method was not used in the context typically seen in AI device studies. The primary goal was to demonstrate image production and quality consistent with the predicate, not diagnostic accuracy against a ground truth.

4. 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, an MRMC comparative effectiveness study was not done. This submission is for a medical device (MRI coil), not an AI-assisted diagnostic tool. The document explicitly states: "The subject of this premarket submission, 1.5T 4CH Flex Coil did not require external clinical studies to support substantial equivalence."

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

   • Not applicable. This device is an MRI coil, which is a component of an imaging system, not a standalone algorithm or AI. Its performance is evaluated on its ability to acquire images, not to perform interpretations.

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

   • For the "sample clinical images" obtained from internal scans, the concept of a formal "ground truth" (e.g., pathology, expert consensus on disease presence) in the context of diagnostic accuracy is not applicable or stated. The "ground truth" for the coil's performance was likely related to the expected image quality and signal-to-noise ratio compared to engineering specifications and the predicate device, demonstrated through visual inspection of the images themselves rather than an independent diagnostic gold standard.

7. The sample size for the training set:

   • Not applicable. This is a hardware device (MRI coil), not a machine learning algorithm that requires a training set.

8. How the ground truth for the training set was established:

   • Not applicable. (See point 7).
