Intended Use

The MAGNETOM system with the 6 Channel Body Coil is a whole body scanner. The MAGNETOM system with the 6 Channel Body Coil is indicated for use as diagnostic imaging device to produce transversal, sagittal, coronal and oblique images of the internal structures of the body. The images produced by the MAGNETOM system with the 6 Channel Body Coil reflect the spatial distribution of protons (hydrogen nuclei) exhibiting magnetic resonance. The MR 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 determining a diagnosis.

Device Story

6 Channel Body Coil is an accessory for MAGNETOM MRI systems; functions as a radiofrequency receiver coil to capture magnetic resonance signals from protons in the body. Input: magnetic resonance signals; Output: raw data for image reconstruction. Used in clinical settings by trained physicians/technicians to produce diagnostic images of internal body structures. Device enhances signal-to-noise ratio (SNR) and image uniformity compared to standard coils. Output interpreted by physicians to determine diagnosis based on proton density, T1, T2, and flow properties. Benefits patient by providing high-quality diagnostic imaging for clinical assessment.

Clinical Evidence

Bench testing only. Testing focused on Signal-to-Noise Ratio (SNR) and image uniformity. Results demonstrated equivalence to predicate MAGNETOM system coils.

Technological Characteristics

6-channel phased-array body coil for MRI. Designed for integration with MAGNETOM Symphony/Sonata systems. Sensing principle: magnetic resonance signal reception. Performance specifications include SNR, image uniformity, geometric distortion, and high-contrast spatial resolution. No changes to static field strength, RF power deposition, or acoustic noise levels compared to predicate systems.

Indications for Use

Indicated for use as a diagnostic imaging device for whole body scanning in patients requiring transversal, sagittal, coronal, and oblique MR imaging of internal body structures.

Regulatory Classification

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).

Special Controls

*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 Description:

#### • Intended Use

The MAGNETOM system with the 6 Channel Body Coil is a whole body scanner. The MAGNETOM system with the 6 Channel Body Coil is indicated for use as diagnostic imaging device to produce transversal, sagittal, coronal and oblique images of the internal structures of the body. The images produced by the MAGNETOM system with the 6 Channel Body Coil reflect the spatial distribution of protons (hydrogen nuclei) exhibiting magnetic resonance.

When interpreted by a trained physician, these images provide information that can be useful in determining a diagnosis.

#### · Technological Characteristics

The MAGNETOM systems with the new 6 Channel Body Coil is substantially equivalent to the predicate MAGNETOM systems.

#### · General Safety and Effectiveness Concerns:

Operation of the MAGNETOM Symphony/Sonata and Upgrades to Symphony/Sonata systems with the 6 Channel Body Coil is substantially equivalent to standard operation of the commercially available MAGNETOM Symphony/Sonata/Upgrades to Symphony/Sonata systems. The following safety parameter with action levels:

- -Maximum Static Field Strength
- Rate of Change in Magnetic Field -
- RF Power deposition -
- Acoustic Noise Levels -

and performance levels:

- Specification Volume -
- Signal to Noise -
- Image Uniformity -
- -Geometric distortion
- High contrast spatial resolution -
- Slice profile, thickness and gap -

specified by the FDA guidance document for MR Diagnostic Devices are unaffected by the modifications described within this notification. The 6 Channel Body Coil was tested for SNR and Image uniformity and the results

presented in this submission show that they are equivalent with the predicate devices described in this submission.

#### • Substantial Equivalence:

Laboratory and clinical testing were performed to support this claim of substantial equivalence and to show that the technological differences do not raise any new questions pertaining to safety and effectiveness.

Dear Mr. Yieh:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA), You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898.
