The document describes a receive-only MR coil and its performance metrics (SNR, uniformity), with no mention of AI, ML, or image processing beyond the basic function of the coil.
No
The device is described as a "diagnostic imaging device" used to produce images for determining a diagnosis, rather than for treatment.
Yes
The "Intended Use / Indications for Use" section explicitly states that the device is "indicated for uses as a diagnostic imaging device". It further explains that the images produced "provide information that can be useful in determining a diagnosis."
No
The device description explicitly states that the device is a "receive only MR coils for imaging the human head" and describes physical components like a "split design" and an "addition mirror," indicating it is a hardware device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The description clearly states that this device is a "receive only MR coil for imaging the human head." It works in conjunction with a Magnetic Resonance Scanner to produce images of the internal structures of the body.
- Intended Use: The intended use is for "MR examination of the human head" and to "produce transversal, sagittal, coronal and oblique images of the internal structures of the body." These images are then interpreted by a trained physician for diagnosis.
- No Sample Analysis: The device does not analyze any biological samples taken from the patient. It directly interacts with the patient's body using magnetic fields to generate images.
Therefore, this device falls under the category of medical imaging devices, not in vitro diagnostics.

Device Description
The 1.5T 32-channel Head Coil and the 3T 32-channel Head Coil are receive only MR coils for imaging the human head. The coils comprises a split design for easy patient positioning. An addition mirror is provided for patient comfort. A high number of 32 receive elements has been chosen to make use of high acceleration factors in the so-called parallet imaging technique (iPAT). The inner dimensions of the coil have been chosen to be smaller than the Head Matrix Coil to optimize the signal-tonoise ratio.

(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.

Dear Mr. Preiss:
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 either class II (Special Controls) or class III (PMA), it may be subject to such 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); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market. .
