The document describes a physical head coil for an MRI machine and does not mention any software or algorithms that would incorporate AI or ML.
No.
The device is used to obtain diagnostic images for the purpose of helping a physician determine a diagnosis, not to treat a condition.
Yes.
The device is used to obtain diagnostic images that, when interpreted by a trained physician, yield information useful in determining a diagnosis.
No
The device description clearly states it is a "16 z-element quadrature transmit receive coil" with "coil elements and associated circuitry enclosed in a rigid former," indicating it is a physical hardware component used in MRI.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening.
- Device Function: The Magnetom Symphony Quadrature Head Coil is a component of a Magnetic Resonance Imaging (MRI) system. Its function is to transmit and receive radiofrequency signals to create images of the inside of the body. It does not analyze biological specimens.
- Intended Use: The intended use is to obtain diagnostic images of the head and surrounding areas using MRI. These images are then interpreted by a trained physician to aid in diagnosis. This is an in vivo (within the living body) diagnostic process, not in vitro.
The device description and intended use clearly indicate that this is a medical imaging device used directly on a patient, not a device for testing samples outside the body.

Intended Use / Indications for Use
The Magnetom Symphony Quadrature Head Coil is a quadrature transmit receive coil used for obtaining diagnostic images of the head at the 1.5Tesla field strength in Magnetic Resonance Imaging. The indications for use are the same as for standard MR imaging. The Magnetom Symphony Head Coil is designed for use with the Siemens Magnetom Symphony 1.5Tesla MRI Scanner.
The Magnetom Symphony Head Coil is designed to manutious retic Resonance Images of the brain, cervical spine, soft tissues and provide wagnetie head, neck and upper chest. The Magnetom Symphony Head Coil is designed for use with the Magnetom Symphony 1.5Tesla scanner manufactured by Siemens Medical Systems.
The indications for use are the same as for standard imaging:
The 1.5Tesla MRI system is indicated for use as an NMR device that produces images that: (1) correspond to the distribution of protons exhibiting NMR signal, Intagoo that: (1) conceptrameters (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 yield information that can be useful in the determination of a diagnosis.

Device Description
The Magnetom Symphony Head Coil is a 16 z-element quadrature transmit receive coil. The coil elements and associated circuitry are enclosed to prevent any exposure to patient or environment. The coil electronics are enclosed in a rigid former. The former is a split top design with latching device and a large open viewing window on the top. The coil design facilitates the scanning of patients with different head sizes and maximizes patient comfort and ease of use.

§ 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.
