AI/ML Overview

The provided text describes a 510(k) summary for the "3T 32 Channel Head Coils." This document focuses on demonstrating substantial equivalence to a predicate device rather than presenting a study to prove a device meets specific clinical acceptance criteria for diagnostic performance.

Therefore, many of the requested details, such as sample size for test sets, number of experts for ground truth, adjudication methods, MRMC studies, standalone algorithm performance, or ground truth for training sets, are not applicable to this type of submission.

The acceptance criteria and performance data provided are related to the safety and engineering characteristics of the head coil, ensuring it functions as intended and is safe for use in conjunction with an MRI scanner.

Here's the breakdown of the available information:

1. Table of Acceptance Criteria and Reported Device Performance

Acceptance Criteria (Internal Requirements, National/International Standards)Reported Device Performance
Biocompatibility testing per ISO 10993-1Passed
Electrical safety testing per IEC 60601-1Passed
Electrostatic discharge testing per IEC 61000-4-2 (per IEC 60601-1-2)Passed
Safety & essential performance of magnetic resonance equipment per IEC 60601-2-33Passed
Magnetic Resonance Diagnostic Devices Testing per NEMA MS 6Passed
Transport Testing per ISTA Procedure 2BPassed
Performance Testing (Internal, design & development process)Results deemed acceptable
Clinical Image QualityAcceptable Image Quality

Regarding the other requested information:

2. Sample sized used for the test set and the data provenance:

  • Test Set Sample Size: Not applicable. The performance testing described relates to engineering and safety standards, not a clinical diagnostic performance test on a specific patient dataset.
  • Data Provenance: Not applicable for a clinical diagnostic test set. The clinical images obtained were to demonstrate acceptable image quality.

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

  • Number of Experts: Not applicable for a diagnostic performance ground truth.
  • Qualifications: "A Chief Medical Physicist" certified the acceptable image quality of the clinical images.

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

  • Not applicable. There was no diagnostic test set requiring adjudication in this submission.

5. 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. This submission is for an MRI head coil, not an AI-powered diagnostic algorithm. Therefore, an MRMC study related to AI assistance is not applicable.

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

  • No. This is an MRI head coil, not a standalone diagnostic algorithm.

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

  • For the engineering and safety tests, the "ground truth" is adherence to established national and international standards (e.g., ISO, IEC, NEMA).
  • For clinical images, the "ground truth" was an assessment of acceptable image quality by a Chief Medical Physicist. This is a technical assessment of image integrity, not a diagnostic accuracy ground truth.

8. The sample size for the training set:

  • Not applicable. This device does not involve a "training set" in the context of an AI/machine learning algorithm.

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

  • Not applicable, as there is no training set for this device.

Trade/Device Name: 3T 32 Channel Head Coils Regulation Number: 21 CFR 892.1000 Regulation Name: Magnetic resonance diagnostic device Regulatory Class: Class II Product Code: MOS Dated: March 22, 2019 Received: March 25, 2019

Dear Ms. Powell:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see

{6}------------------------------------------------

https://www.fda.gov/CombinationProducts/GuidanceRegulatoryInformation/ucm597488.htm); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm.

For comprehensive regulatory information about medical devices and radiation-emitting products, including information about labeling regulations, please see Device Advice (https://www.fda.gov/MedicalDevices/DeviceRegulationandGuidance/) and CDRH Learn (http://www.fda.gov/Training/CDRHLearn). Additionally, you may contact the Division of Industry and Consumer Education (DICE) to ask a question about a specific regulatory topic.

§ 892.1000 Magnetic resonance diagnostic device.

(a)
Identification. A magnetic resonance diagnostic device is intended for general diagnostic use to present images which reflect the spatial distribution and/or magnetic resonance spectra which reflect frequency and distribution of nuclei exhibiting nuclear magnetic resonance. Other physical parameters derived from the images and/or spectra may also be produced. The device includes hydrogen-1 (proton) imaging, sodium-23 imaging, hydrogen-1 spectroscopy, phosphorus-31 spectroscopy, and chemical shift imaging (preserving simultaneous frequency and spatial information).(b)
Classification. Class II (special controls). A magnetic resonance imaging disposable kit intended for use with a magnetic resonance diagnostic device only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.
