## Intended Use

The GE 1.5T 8 Channel Torso Coil is intended to be used in the abdomen, pelvis and chest regions for 2D and 3D Magnetic Resonance imaging and Parallel body imaging.

## Device Story

GE 1.5T 8 Channel Torso Coil is a 12-element phased array MRI coil with integrated preamplifiers; designed for imaging abdomen, pelvis, and chest. Device utilizes optimized geometry to support parallel imaging (ASSET) techniques. Operated by MRI technicians/radiologists in clinical settings; output is raw signal data processed by the MRI system to generate diagnostic images. Benefits include improved imaging performance and parallel imaging capabilities for torso applications. Substantially equivalent to existing phased array coils; no new hazards introduced.

## Clinical Evidence

Bench testing only. Testing was performed to demonstrate that the design of the 1.5T 8 Channel Torso Coil met predetermined acceptance criteria.

## Technological Characteristics

12-element phased array MRI coil; integrated preamplifiers; optimized geometry for parallel imaging (ASSET). Designed for 1.5T MRI systems. Connectivity is via standard MRI coil interface.

## Regulatory 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 Name:

GE 1.5T 8 Channel Torso Coil Magnetic Resonance Coil, 21 CFR 892.1000, 90-MOS

# Marketed Device:

The GE 1.5T 8 Channel Torso Coil is substantially equivalent to the currently marketed GE the 3.0T Torso Phased Array Coil (K030495) with the integration of the 8 channel technology in the currently marketed GE 8 Channel Cardiac Phased Array Coil (K022669).

# Device Description:

The GE 1.5T 8 Channel Torso Coil is a 12 element coil with integrated preamplifiers that provides optimized geometry for parallel imaging. The coil is designed to provide imaging of the abdomen, pelvis and chest regions. The device utilizes technology similar to the GE 8 Channel Cardiac Phased Array Coil (K022669), but is designed to image the torso, similar to the GE 3.0T Torso Phased Array Coil (K030495).

### Indications for Use:

The GE 1.5T 8 Channel Torso Coil is intended to be used in the abdomen, pelvis and chest regions for 2D and 3D Magnetic Resonance imaging and Parallel body imaging.

# Comparison with Predicate Device:

The GE 1.5T 8 Channel Torso Coil is a modification of the GE 3.0T Torso Phased Array Coil (K030495), which presents an increase in the number of coil elements from four to twelve, and integrates the preamplifiers similar to the GE 8 Channel Cardiac Phased Array Coil (K022669). The GE 1.5T 8 Channel Torso Coil utilizes optimized geometry for parallel imaging (ASSET).

# Summary of Studies:

Testing was performed to demonstrate that the design of the 1.5T 8 Channel Torso Coil meet predetermined acceptance criteria.

# Conclusion:

It is the opinion of GE that the GE 1.5T 8 Channel Torso Coil is substantially equivalent to the GE 3.0T Torso Phased Array Coil (K030495), and the GE 8 Channel Cardiac Phased Array Coil (K022669). The usage of the GE 1.5T 8 Channel Torso Coil does not result in any new potential hazards.

Dear Dr. Kroger:

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. In addition, FDA may publish further announcements concerning your device in the Federal Register.
