The document describes standard MR imaging techniques (Fourier transformation) and does not mention any AI/ML terms or functionalities.
No
The device is described as a diagnostic imaging device that assists in diagnosis by producing images and/or spectra for a trained physician's interpretation, not for therapeutic purposes.
Yes
The "Intended Use / Indications for Use" section explicitly states that the "Signa® 3.0T with Excite MR System is indicated for use as a diagnostic imaging device." It also mentions that the images and/or spectra "may assist in diagnosis" when interpreted by a trained physician.
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 not solely software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body, such as blood, urine, or tissue, to provide information for diagnosis, monitoring, or screening.
- Device Function: The GE Signa® 3.0T with Excite is a Magnetic Resonance (MR) scanner. It produces images of the internal structures of the body in vivo (within the living body) using magnetic fields and radio waves. It does not analyze samples taken from the body.
- Intended Use: The intended use clearly states it's a "diagnostic imaging device to produce... images... of the internal structures and organs of the entire body." This is consistent with an imaging device, not an IVD.
Therefore, the GE Signa® 3.0T with Excite is a medical imaging device, not an In Vitro Diagnostic.

Device Description
The GE Signa 3.0T with Excite Magnetic Resonance System is a modification to the Signa® 3.0T Magnetic Resonance System (K022397) which utilizes a superconducting magnet to acquire 2D single-slice and multi-slice, and 3D volume images. The GE Signa® 3.0T with Excite Magnetic Resonance System features a superconducting magnet operating at 3.0T. 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, short scan times, and multinuclear spectroscopy.

§ 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.
