No
The summary describes a passive RF coil for MRI, which is a hardware component for signal acquisition. There is no mention of software, algorithms, or data processing that would suggest the use of AI/ML.
No
The device is described as a receive-only RF coil used for obtaining diagnostic images in Magnetic Resonance Imaging Systems, with the primary purpose of yielding information useful in determining a diagnosis, not providing therapy.
Yes
The device is described as producing images that, when interpreted by a trained physician, "yield information that can be useful in the determination of a diagnosis," directly linking its output to diagnostic purposes.
No
The device is described as a "receive-only phased array RF coil" with physical components like "elements and associated circuitry are enclosed in a housing made of plastic materials." This clearly indicates a hardware device, not software only.
Based on the provided text, 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 an RF coil used in Magnetic Resonance Imaging (MRI) systems to obtain diagnostic images of the spine. MRI is an imaging modality that uses magnetic fields and radio waves to create images of the inside of the body. It does not involve testing samples taken from the body.
- Intended Use: The intended use is to obtain diagnostic images of the spine, which are then interpreted by a trained physician to aid in diagnosis. This is a direct imaging process, not an in vitro test.
Therefore, the 3.0T 4-Channel Cervico-Thoracic-Lumbar (CTL) Array Coil is a medical device used for in vivo imaging, not an in vitro diagnostic device.

Intended Use / Indications for Use
The 3.0T 4-Channel Cervico-Thoracic-Lumbar (CTL) Array Coil is a receive-only phased array RF coil, used for obtaining diagnostic images of the spine (cervical, thoracic and lumbar regions) in Magnetic Resonance Imaging Systems. The indications for use are the same as for standard MR Imaging. The 3.0T 4-Channel Cervico-Thoracic-Lumbar (CTL) Array Coil is designed for use with the GE Medical Systems 3.0Tesla MRI scanner.
The 3.0T 4-Channel Cervico-Thoracic-Lumbar (CTL) Array Coil is designed to provide Magnetic Resonance Images of the cervical, thoracic, and lumbar regions of the spine. The 3.0T 4-Channel Cervico-Thoracic-Lumbar (CTL) Array Coil is designed for use with the GE 3.0T scanner manufactured by GE Medical Systems, Inc.
Anatomic Regions: cervical, thoracic, and lumbar regions of the spine
Nuclei Excited: Hydrogen
The indications for use are the same as for standard imaging:
The 3.0T MRI system is indicated for use as an NMR device that produces images that: (1) correspond to the distribution of protons exhibiting NMR signal, (2) depend upon NMR parameters (proton density, spin lattice relaxation time T1, spin-spin relaxation time T2) and (3) display the soft tissue structure of the head and whole body. When interpreted by a trained physician, these images vield information that can be useful in the determination of a diagnosis.

§ 892.1000 Magnetic resonance diagnostic device.
(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.
