Intended Use

The Infant Array is a receive-only RF coil, used for obtaining high resolution images and spectra of the infant brain, spine, heart, torso and extremity in GE, Siemens and Philips 1.5T and 3.0T magnetic resonance imaging systems and magnetic resonance compatible incubators. Indications for use are same as that for standard MR imaging and spectroscopy.

The Infant Array when used in conjunction with GE, Siemens and Philips 1.5T and 3T MRI systems or Infant Array when used with the MRI compatible incubator and in conjunction with the abovementioned MRI systems provide imaging of the infant's brain, spine, heart, torso and extremities. When interpreted by a trained physician, these images provide information that can be useful in the determination of the diagnosis.

Device Description

The Infant Array is a 20-element receive-only radio-frequency (RF) coil array well suited for routine and parallel imaging. The Infant Array (IA) consists of an Infant Head Spine Array (IHSA) and an anterior Cardiac section (CAR). The IHSA can be used alone for spine and brain examinations or in conjunction with the anterior cardiac section necessary for cardiac and torso MRI exams. The anterior cardiac section cannot be used alone. This anterior cardiac section is supported on a sliding adjustable height gantry. Coil elements and associated circuitry are enclosed in a rigid former to prevent any exposure to patient or environment. The plastic materials used are fire rated and have a high impact and tensile strength. The coil design facilitates scanning of low birth weight pre-term babies, term newborns and small infants with different body sizes and maximizes comfort and ease of use.

20 element, receive-only RF coil array. The Infant Array consists of two sections: infant head spine array (IHSA) and anterior cardiac section (CAR), which is positioned above the IHSA and supported on a sliding adjustable height gantry. Coil elements and associated circuitry are enclosed in a rigid former to prevent any exposure to patient or environment.

AI/ML Overview

Here's a summary of the acceptance criteria and study information for the Infant Array device, based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance:

The document broadly states that "Testing was performed to demonstrate that the Infant Array meet the predetermined acceptance criteria." However, specific numerical acceptance criteria (e.g., signal-to-noise ratio requirements, specific image quality metrics) are not explicitly defined or reported within the provided text. The performance is primarily described through its intended use and similarity to predicate devices.

Acceptance Criteria (Not Explicitly Stated as Numerical)Reported Device Performance (Implied by equivalence and intended use)
Ability to obtain high-resolution images and spectra.Capable of obtaining high resolution images and spectra of the infant brain, spine, heart, torso and extremity.
Compatibility with specified MRI systems.Compatible with GE, Siemens, and Philips 1.5T and 3.0T MRI systems and MRI compatible incubators.
Safety with regard to RF decoupling, prevention of RF burns, RF absorption.Decoupling with RF chokes and fast-acting pin-diode switching diodes (similar to predicate). Does not transmit RF power. Coil elements and associated circuitry enclosed in non-conductive plastic housing. Active diodes and RF fuses isolate coil elements; length and routing of output cable does not permit looping (similar to predicate).
Ability to provide information useful for diagnosis when interpreted by a trained physician.Images provide information that can be useful in the determination of the diagnosis (when interpreted by a trained physician).

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

The document does not specify the sample size used for the test set or the data provenance (e.g., country of origin, retrospective/prospective). It generally mentions "testing" and "usage," but no details on the patients or data used, or how they were collected.

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

The document does not provide any information on the number of experts used to establish ground truth or their qualifications. It only states that images should be "interpreted by a trained physician."

4. Adjudication Method for the Test Set:

The document does not mention any adjudication method for the test set.

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

The document does not indicate that a multi-reader multi-case (MRMC) comparative effectiveness study was done. The focus is on demonstrating substantial equivalence to predicate devices, not on comparing reader performance with and without AI assistance.

6. Standalone Performance Study:

The document does not explicitly state that a standalone (algorithm only without human-in-the-loop performance) study was performed. The device is a hardware component (RF coil), not an algorithm. The testing would have focused on the physical and functional performance of the coil itself.

7. Type of Ground Truth Used:

The document does not specify the type of ground truth used, as it doesn't detail specific performance metrics beyond the general ability to obtain images useful for diagnosis. Given that the device is an RF coil, the "ground truth" would likely relate to objective image quality metrics (e.g., SNR, image uniformity, spatial resolution) rather than disease detection or classification which would involve a separate diagnostic algorithm or human interpretation.

8. Sample Size for the Training Set:

The document does not mention a training set sample size. As the Infant Array is a hardware device (RF coil) and not a machine learning algorithm, the concept of a "training set" in the context of AI/ML models is not directly applicable.

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

The concept of "ground truth for the training set" is not applicable to this device, as it is a hardware component rather than an AI/ML diagnostic tool.

Dear Mr. Srinivasan:

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. 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.

If your device is classified (see above) into class II (Special Controls), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. 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 Parts 801 and 809); medical device reporting (reporting of
