No
The description focuses on the hardware components (RF coils) and their function in receiving MRI signals. There is no mention of AI, ML, or any software processing beyond basic signal amplification and transfer to the scanner for image generation.
No
The device is used to produce diagnostic images, not for therapeutic purposes.
Yes
Explanation: The "Intended Use / Indications for Use" section explicitly states, "When used as intended, the 32Ch AIR Open Coil Suite is used to produce diagnostic images of the head, neck, and brachial plexus structures." While the coils themselves are components of an MRI system, their intended purpose is to facilitate the creation of images that are then interpreted for diagnostic purposes.
No
The device description explicitly states it is comprised of "MRI receive-only phased array RF coils," which are hardware components. The performance studies also detail bench testing on physical characteristics like electrical safety, surface temperature, and blocking network analysis, further indicating it is a hardware device.
Based on the provided text, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for the diagnosis, treatment, or prevention of disease.
- Device Function: The 32Ch AIR Open Coil Suite is an MRI RF Receive-Only Coil. Its function is to receive magnetic resonance signals from within the patient's body during an MRI scan. It does not interact with specimens taken from the body.
- Intended Use: The intended use is to produce diagnostic images of the head, neck, and brachial plexus structures within the patient's body.
Therefore, the device's function and intended use clearly fall outside the scope of In Vitro Diagnostics. It is a component of an imaging system used for in vivo (within the living body) diagnosis.

Device Description
The 32Ch AIR Open Coil Suite is comprised of MRI receive-only phased array RF coils designed for clinically acceptable signal-to-noise ratio (SNR) and uniform coverage of the Head, Neck and Brachial Plexus anatomy for use with GE Healthcare Magnetic Resonance Imaging (MRI) scanners. The 32Ch AIR Open Coil Suite consists of the following arrays available in 1.5T and 3.0T field strengths:
- AIR Open Head Neck Posterior 9ch
- AIR Open Neck Chest Anterior 7ch
- AIR Open Head Anterior 16ch .
The coils receive magnetic resonance signals generated in hydrogen nuclei (protons) in the Head, Neck and Brachial Plexus anatomy while blocking the high-frequency magnetic field applied by the MRI scanner at specified timings. The received signals are amplified before being transferred to the MRI scanner through the coil's system cable. The amplified signals are processed by the MRI scanner into tomographic images of the Head, Neck and Brachial Plexus anatomy by the MRI scanner. Images are tvpically generated as axial, sagittal, coronal oblique slices. There are no accessories associated with the 32Ch AIR Open Coil Suite. Depending on the region of interest, the coils may be used in combination with the CIVCO RT Universal Couchtop™ MR Overlay for GE Motus, Kizuna, and GEM as well as the associated patient immobilization devices (e.g., thermoplastic mask, straps provided with the MRI scanner)
The 1.5T 32Ch AIR Open Coil Suite and the 3.0T 32Ch AIR Open Coil Suite are tuned to receive RF frequency corresponding to the proton precession in a 1.5 tesla and 3.0 tesla magnetic field (respectively), which is governed by the Larmor equation.
The 32Ch AIR Open Coil Suite is intended for use in a manner that is identical to the predicate device described in this submission.
Proposed labeling is documented in the Instructions for Use manual for the 32Ch AIR Open Coil Suite (NC139IFU-en).
