## Intended Use
The Nova Medical 3T 32 Channel Head Coil is to be used in conjunction with a Magnetic Resonance (MR) Scanner to produce images and/or spectra of the head, that when interpreted by a trained physician yield information that may assist in diagnosis. Model # 3832016 is used with GE 3T MRI Scanner Discovery MR750. Model # 38320169 is used with GE 3T MRI Scanners Signa Architect, Discovery MR750W and Signa PET/MR.
## Device Story
3T 32 Channel Head Coil is a receive-only MRI accessory for GE 3T MR systems; used for neuroimaging, fMRI, and spectroscopy. Device features 32 RF elements tuned to 127.75 MHz; constructed of two-part rigid plastic housing with patient viewing opening. Includes optional mirror and foam cushions for positioning. Operated by MRI technicians in clinical settings; coil receives RF signals from patient head during scan. Output is raw MR signal processed by the host scanner into images/spectra for physician interpretation to assist in diagnosis. Split design facilitates patient positioning; device is non-software, passive hardware.
## Clinical Evidence
Clinical images were obtained per FDA guidance for Magnetic Resonance Diagnostic Devices. Images were evaluated and certified by a Chief Medical Physicist as having acceptable image quality. No formal clinical trial with diagnostic endpoints was required; performance was validated via bench testing and clinical image assessment.
## Technological Characteristics
Receive-only 32-channel phased array head coil; 127.75 MHz resonant frequency. Rigid plastic housing; split design. Dimensions: ~17.5" L x 12" H x 15" W. Biocompatibility per ISO 10993-1. Electrical safety per ANSI/AAMI ES 60601-1, IEC 60601-2-33, and IEC 61000-4-2. Passive device; no internal software or microprocessors.
## Regulatory 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).
## Special Controls
*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 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. See the DICE website (http://www.fda.gov/DICE) for more information or contact DICE by email (DICE@fda.hhs.gov) or phone (1-800-638-2041 or 301-796-7100).
