The dS FootAnkle 16ch 1.5T and 3.0T MR Coils are intended to be used in conjunction with Philips 1.5T/3.0T Magnetic Resonance Scanners to produce diagnostic images of the foot and ankle anatomy that can be interpreted by a trained physician.

The dS HiRes Hand/Wrist 16ch 1.5T and 3.0T MR Coils are intended to be used in conjunction with Philips 1.5T/3.0T Magnetic Resonance Scanners to produce diagnostic images of the hand and wrist anatomy that can be interpreted by a trained physician.

The dS Small Extremity 16ch 1.5T and 3.0T MR Coils are intended to be used in conjunction with Philips 1.5T/3.0T Magnetic Resonance Scanners to produce diagnostic images of the small extremities anatomy on adult and pediatric patients that can be interpreted by a trained physician.

Device Description

The Philips Orthopedic MR Coils are designed for use with Magnetic Resonance Imaging (MRI) systems. The coils are designed to work in unison with the Body Coil of the MRI system, which will transmit the radio frequency (RF) signals, so that the coil may receive the resultant RF signal from the excited nuclei.

The subject devices have 16-elements and are for use with Philips Ingenia 1.5T and 3.0T MR Systems with dStream interface (K193215). The devices are designed for optimum coverage and high-resolution visualization of detailed cartilage structures of the body anatomy (foot/ankle, hand/wrist, small extremity). The coil is used independently and cannot be combined with any other coils. The coils are available in both 1.5T and 3.0T magnetic strengths.

AI/ML Overview

The provided text outlines the performance testing for the Philips Orthopedic MR Coils, but it does not contain details on acceptance criteria or performance data as would be found in a study proving a device meets specific acceptance criteria in the context of an AI/ML diagnostic device regulatory submission. The document is a 510(k) summary for magnetic resonance coils, which are hardware components, not artificial intelligence software.

Therefore, I cannot fulfill your request for details regarding:

A table of acceptance criteria and reported device performance (in the context of AI/ML diagnostic output).
Sample sizes for test sets or data provenance (as there's no AI algorithm being tested).
Number of experts or their qualifications, or adjudication methods (as this pertains to evaluating AI output against ground truth).
MRMC comparative effectiveness studies.
Standalone algorithm performance.
Type of ground truth used.
Training set information.

The document focuses on the substantial equivalence of the MR coils to predicate devices based on:

Physical characteristics (design, material, chemical composition, energy source).
Adherence to recognized standards for MR coil performance (e.g., NEMA MS 1, 3, 9, IEC 62464-1 for image quality; ANSI/AAMI ES 60601-1, NEMA MS 14 for surface heating).
General electrical/mechanical safety (IEC 60601-2-33, AAMI/ANSI ES 60601-1).
Biocompatibility (ISO 10993 series).

The closest mention of "image quality assessment by a U.S. Board Certified radiologist" just confirms that the images produced were "sufficient quality for diagnostic use," but this is a general statement and not a quantitative performance metric against specific acceptance criteria for a diagnostic algorithm.

Dear Prithul Bom:

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.

{1}------------------------------------------------

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 https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); 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 https://www.fda.gov/medical-device-safety/medical-device-reportingmdr-how-report-medical-device-problems.

Fundamental Scientific Technology:	The subject Philips Orthopedic MR Coils are consideredsubstantially equivalent to the primary currently marketedpredicate devices (dS FootAnkle 16Ch Coil for 1.5T, InvivoCorporation, K162177 cleared on 09/14/2016; Hand-Wrist Coil16Ch Coil for 1.5T, Invivo Corporation, K103149 cleared on01/03/2010; and dS Small Extremity 16Ch 1.5T Coil, InvivoCorporation, K162863 cleared on 11/7/2016) in terms offundamental scientific technology.The subject coils are similar in design, material, chemicalcomposition and energy source to the legally marketed predicatedevices.
	At a high level, the subject coils as part of this submission and the predicate devices are based on the following same technological elements: Prescription use Coil designs are receive-only phased array coils Decoupling methodology Patient contacting materials and chemical composition are known materials that have been assessed for compliance with recognized biocompatibility standards Energy source for the coils is the MRI scanner No energy is supplied by the coils Coils designs are targeted for imaging the anatomy of interest Mechanical designs are contoured for the patient anatomy The following technological differences exist between the subject and predicate devices:
	Coil geometry housing design: Housing with similar design. Subject housing design is slightly different design to more closely mimic subject patient anatomy and provide additional patient comfort. System compatibility: New coil compatible with 3.0T MR scanner.
	The intended use for subject coils is the same as for the predicate device, specifically the coils are intended to be used in conjunction with a Magnetic Resonance Scanner to produce diagnostic images that can be interpreted by a trained physician; only differing in name of the coil and the reference to the specific body part (e.g., foot and ankle vs anatomy of interest). For the dS Small Extremity 16Ch Coils for 1.5T and 3.0T , it was also determined that the coils can be used to assess both adult and pediatric patients which has been added to the indications for use.
