Intended Use
The GE Signa Infinity line of products are whole body magnetic resonance scanners designed to support high resolution, high signal-to-noise ratio and short scan times. The Signa Infinity System is indicated for use as a diagnostic imaging device to produce transverse, sagittal, coronal and oblique images, spectroscopic images, and/or spectra, dynamic images of the internal structures and organs of the entire body, including, but not limited to, head, neck, TMJ, spine, breast, heart, abdomen, pelvis, joints, prostate, blood vessels, and musculoskeletal regions of the images produced by the Signa Infinity systems reflect the spatial distribution of protons (hydrogen nuclei) exhibiting magnetic resonance. These images and/or spectra when interpreted by a trained physician yield information that may assist in diagnosis.
Device Description
The Signa Infinity Magnetic Resonance System is a modification to the Signa TwinSpeed Magnetic Resonance System (K012200) which utilizes a superconducting magnet to acquire 2D single-slice and multi-slice, and 3D volume images. The Signa Infinity Magnetic Resonance System features a superconducting magnet operating at 1.5T. The system can image in the sagittal, coronal, axial, oblique and double oblique planes, using various pulse sequences. Images are acquired and reconstructed using 2D and 3D Fourier transformation techniques. The system is intended for high resolution anatomical applications and short scan times. Previously cleared software options, coils, and other accessories may · be used with the Signa Infinity Magnetic Resonance System.
More Information

No
The document describes standard MRI technology and image reconstruction techniques (Fourier transformation) without mentioning AI or ML.

No.
The device is described as a "diagnostic imaging device" used to produce images that "may assist in diagnosis," not to provide therapy.

Yes

The "Intended Use / Indications for Use" section explicitly states, "The Signa Infinity System is indicated for use as a diagnostic imaging device to produce... images and/or spectra when interpreted by a trained physician yield information that may assist in diagnosis."

No

The device description clearly states it is a "Magnetic Resonance System" which includes a superconducting magnet and other hardware components for acquiring images. It is a physical imaging device, not solely software.

Based on the provided text, the GE Signa Infinity line of products is not an IVD (In Vitro Diagnostic) device.

Here's why:

  • IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) in vitro (outside the body). The Signa Infinity is a magnetic resonance scanner that images the internal structures and organs of the body in vivo (within the body).
  • The intended use clearly states it's a "diagnostic imaging device" to produce images of internal structures. This is the core function of an imaging system, not an IVD.
  • The device description details a superconducting magnet and imaging techniques. These are characteristic of an MRI system, not an IVD.

Therefore, the GE Signa Infinity is a medical imaging device, not an In Vitro Diagnostic device.

§ 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.

Device Name:

GE Signa Infinity Magnetic Resonance System Magnetic Resonance Diagnostic System, 21 CFR 892.1000, 90-LNH

Marketed Device:

The Signa Infinity System is substantially equivalent to the currently marketed Signa TwinSpeed MR system (K012200) with the main differences being an addition of eight independent receive channels and an update of the technology used for the Computer subsystem as well as the RF Pulse Control subsystem. In addition, ASSET imaging (K012970) is now offered for eight receive channels.

Device Description:

The Signa Infinity Magnetic Resonance System is a modification to the Signa TwinSpeed Magnetic Resonance System (K012200) which utilizes a superconducting magnet to acquire 2D single-slice and multi-slice, and 3D volume images. The Signa Infinity Magnetic Resonance System features a superconducting magnet operating at 1.5T. The system can image in the sagittal, coronal, axial, oblique and double oblique planes, using various pulse sequences. Images are acquired and reconstructed using 2D and 3D Fourier transformation techniques. The system is intended for high resolution anatomical applications and short scan times. Previously cleared software options, coils, and other accessories may · be used with the Signa Infinity Magnetic Resonance System.

may assist in diagnosis.

Comparison with Predicate Device:

The Signa Infinity System is a modification of the Signa TwinSpeed MR system (K012200) with the main differences being the addition of eight independent receive channels and an update of the technology used for the Computer subsystem as well as the RF Pulse Control subsystem. Whereas these modifications are generally applicable across a range of field strengths, gradient and RF subsystems, the initial scope is limited to systems comparable to the currently marketed Signa TwinSpeed (K012200) 1.5T Magnetic Resonance Systems.

Summary of Studies:

The Signa Infinity Magnetic Resonance System was evaluated to the appropriate NEMA performance standards as well as the IEC 601-1 International Medical Equipment Safety standard and IEC 601-2-33 Particular Requirements for Safety of Magnetic Resonance Equipment for Medical Diagnosis. The Signa Infinity Magnetic Resonance System is comparable to the currently marketed Signa TwinSpeed Magnetic Resonance System.

Conclusion:

It is the opinion of GE that the Signa Infinity Magnetic Resonance System is substantially equivalent to the Signa TwinSpeed Magnetic Resonance System. Usage of the Signa Infinity Magnetic Resonance System does not result in any new potential hazards.
