No
The document describes a standard MRI system and its imaging capabilities. There is no mention of AI, ML, or any advanced image processing techniques that would typically involve these technologies. The "Imaging processing" mention is likely referring to standard MRI reconstruction and post-processing techniques, not AI/ML-based analysis.
No
The device is described as an "imaging device" intended to provide "physiological and clinical information" useful in "diagnosis determination," clearly indicating its diagnostic rather than therapeutic purpose.
Yes
The device is an imaging system (MRI) that produces images providing information useful in diagnosis determination when interpreted by a trained physician, and its Indications for Use section explicitly lists "Diagnostic uses."
No
The device description explicitly states it is a "1.5T superconducting magnet MRI system," which is a hardware device. While it includes operating software, it is not solely software.
Based on the provided information, the NSM-S15 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.
- NSM-S15 Function: The NSM-S15 is described as an imaging device that produces images of the internal structure of the body using Magnetic Resonance Imaging (MRI). It obtains physiological and clinical information non-invasively.
- Lack of Sample Analysis: The description does not mention the analysis of any biological samples taken from the patient. The device directly images the body.
Therefore, the NSM-S15 falls under the category of medical imaging devices, not In Vitro Diagnostics.
N/A
Intended Use / Indications for Use
The NSM-S15 product is an imaging device, and is intended to provide the physician with physiological and clinical information obtained non-invasively and without the use of ionizing radiation. The MRI system produces transverse, coronal, sagittal, oblique, and curved cross-sectional images that display the internal structure of the head, body, or extremities. The images produced by MRI system reflect the spatial distribution of protons (hydrogen nuclei) exhibiting magnetic resonance. The NMR properties that determine the image appearance are proton density, spin-lattice relaxation time (T1), spin-spin relaxation time (T2), and flow. When interpreted by a trained physician, these images provide information that can be useful in diagnosis determination.
The indications for use are as follows:
Anatomical Region: Head, Shoulder, Breast, Wrist, Body, Spine, Knee, Extremities
Nucleus excited: Proton
Diagnostic uses: T1, T2, proton density weighted imaging
Diffusion weighted imaging
MR Angiography
Imaging processing

§ 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.
