The MR Instruments TEM 3002G-HN Dual Tune headcoil is to be used in conjunction with a 3T Magnetic Resonance Imaging system to produce proton ('H) images and spectra of the internal structures of the head. In addition, sodium (20Na) images and spectra may be obtained during the same exam without changing the coil. These images and/or spectral information of the head, when interpreted by a trained physician, may yield information that may assist in diagnosis. This device is for prescription use.
The TEM 3002G-HN Dual Tune headcoil is a quadrature transmit/receive RF coil tuned to proton ('H) and sodium (22Na) frequencies 3T. The TEM resonant elements and associated matching and quadrature splitting circuitry are enclosed in a rigid plastic housing to prevent any exposure to patient or environment.
The provided text describes the TEM 3002G-HN Dual Tune Headcoil, which is a medical device for Magnetic Resonance Imaging (MRI). However, it is a 510(k) summary for a physical medical device (an MRI headcoil), not an AI/ML powered device. As such, it does not include information on acceptance criteria, a study proving the device meets acceptance criteria, sample sizes for test sets, data provenance, number of experts for ground truth, adjudication methods, MRMC studies, standalone performance, type of ground truth, or training set sample sizes, which are all typically associated with the evaluation of AI/ML diagnostic tools.
Therefore, the prompt cannot be answered with the provided text because it describes a hardware device, not an AI/ML powered diagnostic tool.

| Trade Name: | TEM 3002G-HN Dual Tune headcoil |
| Common Name: | Headcoil |

| Classification: | This device is classified by the RadiologyPanel into Class II, (21 CFR 892.1000) |
3. Device Description
The TEM 3002G-HN Dual Tune headcoil is a quadrature transmit/receive RF coil tuned to proton ('H) and sodium (22Na) frequencies 3T. The TEM resonant elements and associated matching and quadrature splitting circuitry are enclosed in a rigid plastic housing to prevent any exposure to patient or environment.
The predicate devices are also quadrature transmit/receive RF headcoils. All have similar construction, size and shape. All are tuned to proton ('H) resonant frequency at 3T and two are dual resonant, one at phosphorus (31P) and one at carbon (18C).
4. Intended Use
The MR Instruments TEM 3002G-HN Dual Tune headcoil is to be used in conjunction with a 3T Magnetic Resonance Imaging system to produce proton ('H) images and spectra of the internal structures of the head. In addition, sodium (20 a) images and spectra may be obtained during the same exam without changing the coil. These images and/or spectral information of the head, when interpreted by a trained physician, may yield information that may assist in diagnosis.

5. Substantial Equivalence Comparison
The TEM 3002G-HN Dual Tune headcoil is substantially equivalent to the following devices with respect to safety, intended use and design:
| Coil Name | PremarketNotification | Clearance Date |
|---|---|---|
| GE HealthcareSplit Head Coil Assembly for G3, for usewith a Signa 3T MR system for producingproton (1H) MR images and spectra | K040444 | April 14, 2004 |
| Siemens Medical Solutions31P/1H headcoil for MAGNETOM Allegra MRsystem for producing phosphorus (31P) andproton (1H) MR images and spectra | K042617 | November 5, 2004 |
| Siemens Medical Solutions13C/1H headcoil for MAGNETOM Allegra MRsystem for producing carbon (13C) and proton(1H) MR images and spectra | K042718 | November 12, 2004 |
Similarities between the devices are devices in that they are all transmit and receive RF coils designed to work in conjunction with 3T MR System for acquiring proton ('H) diagnostic images and spectra of the internal structures of the head. The double resonance coils are similar in frequency as noted below. In addition, all coils are similar in size, shape and construction.
Note: The resonance frequency of 13C = 32.4 MHz, 22 Na = 33.8 MHz, and 31P = 51.6 MHz at 3T.
The primary differences between the devices are that the TEM 3002G-HN coil adds sodium (22) imaging capability instead of phosphorus (31P) or carbon (130). The GE Healthcare Split Top Coil is not a double resonant coil and requires switching coils to obtain images or spectra at other frequencies.

6. Summary of Studies
Verification and validation testing was performed to ensure that the coil design requirements specification and customer requirements specification were met. Testing activities included electrical bench measurements, electrical/mechanical safety tests, MR system safety and performance tests with phantoms and volunteer scans. MR system tests were conducted using the GE Healthcare Signa 3T MR system running standard clinical applications.
7. Conclusion (statement of equivalence)
The data and information provided in this submission supports a substantial equivalence determination, and, therefore, 510(k) premarket notification clearance of the TEM 3002G-HN Dual Tune headcoil.

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.
