Intended Use

The coil is indicated for use, on the order of a physician in conjunction with a 3.0T MR scanner, as an accessory to produce images of the abdominal and pelvic regions in 2D and 3D. The primary applications associated with evaluation of the anatomy are as follows: Thorax Abdomen Male and Female Pelvis Prostate

Device Story

The 3.0T Torso Phased Array Coil is a four-channel, receive-only MR coil accessory designed for use with GE 3.0T MR systems. It captures magnetic resonance signals from the thorax, abdomen, and pelvic regions (including prostate) to produce 2D and 3D diagnostic images. The device is operated by trained medical personnel in a clinical MR environment. By providing higher field-of-view (FOV) coverage compared to previous 1.5T iterations, it enables high-resolution imaging of abdominal and pelvic anatomy, assisting physicians in clinical diagnosis and evaluation of disease states.

Clinical Evidence

Bench testing only; no clinical data provided.

Technological Characteristics

Four-channel phased array receive-only MR coil; tuned to 127.72MHz for 3.0T operation; dimensions 34cm x 32cm; hardware-based signal reception; compatible with GE 3.0T MR systems.

Indications for Use

Indicated for patients requiring MR imaging of the thorax, abdomen, male/female pelvis, and prostate; used in conjunction with a 3.0T MR scanner under physician order.

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.

Predicate Devices

#### Device Name:

3.0T Torso Phased Array Coil Magnetic Resonance Diagnostic System, 21 CFR 892.1000, 90-MOS

#### Marketed Device:

The 3.0T Torso Phased Array Coil is substantially equivalent to the currently marketed GE Medical Systems 1.5T Cardiac Phased Array (K971667) and USA Instruments Torso and Pelvis Phased Array Coil (K001209).

### Device Description:

The 3.0T Torso Phased Array Coil is a four-channel phased array receive only MR coil used in conjunction with the GE 3.0T MR system.

#### Indications for Use:

The coil is indicated for use, on the order of a physician in conjunction with a 3.0T MR scanner, as an accessory to produce images of the abdominal and pelvic regions in 2D and 3D.

The primary applications associated with evaluation of the anatorny are as follows:

- u Thorax
- . Abdomen
- 트 Male and Female Pelvis
- . Prostate

#### Comparison with Predicate Device:

The 3.0T Torso Phased Array Coil is a modification of the GE Medical Systems 1.5T Cardiac Phased Array Coil (K971667) with the main differences being that the 3.0T

{1}------------------------------------------------

Torso Phased Array Coil is tuned to 127.72MHz for operation at 3.0T instead of 63.86MHz for operation at 1.5T. In addition the dimensions of the 3.0T Torso Phased Array Coil (34cm wide and 32cm long) are larger than the dimensions of the 1.5T Cardiac Phased Array Coil for a higher FOV coverage requirement in case of the 3.0T Torso Phased Array coil. The technological similarities to the USA Instruments Torso and Pelvis Phased Array Coil (K001209) include similar applications and indications for use.

## Summary of Studies:

Testing was performed to demonstrate that the design of the 4 channel 3.0T Torso Phased Array Coil meet predetermined acceptance criteria.

#### Conclusion:

It is the opinion of GE that the 3.0T Torso Phased Array Coil is substantially equivalent to the currently marketed GE Medical Systems 1.5T Cardiac Phased Array Coil (K971667) and USA Instruments Torso and Pelvis Phased Array Coil (K001209). Usage of the 3.0T Torso Phased Array Coil does not result in any new potential hazards.

Dear Mr. Steneberg:

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.
