## Intended Use

The MJAH-137A Atlas SPEEDER Head/Cervical Coil is intended for the use of diagnostic imaging of the human body, fluid visualization, 2D and 3D imaging, MR angiography and MR fluoroscopy. This coil is intended to be used on the Atlas Vantage, model numbers MRT-1503/S3, /S4 and Atlas Titan, model number MRT-1504.

## Device Story

Phased array MRI coil; receives NMR signals from head, cervical region, and upper chest. Configured in three sections: head base, removable anterior coil (head or neck variants), and NV chest coil. Deactivated by PIN diodes during transmit cycle; switches to receive mode upon deactivation. Used in clinical diagnostic imaging environments; operated by trained MRI technicians/radiologists. Provides high-resolution anatomical and functional images for clinical decision-making; aids in visualization of fluid, vasculature, and soft tissue structures.

## Clinical Evidence

Bench testing only. Performance validated via sample phantom images and clinical images demonstrating diagnostic capability.

## Technological Characteristics

Phased array coil; 1.5T static field strength; PIN diode switching mechanism; biocompatible materials; compliant with IEC60601-2-33 (2005) for SAR and dB/dt limits.

## 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.

## Predicate Devices

- Atlas SPEEDER Head ([K063361](/device/K063361.md))
- SPEEDER 1.5T Wrist coil ([K072935](/device/K072935.md))

#### Device Intended Use 6.

The MJAH-137A Atlas SPEEDER Head/Cervical Coil is intended for the use of diagnostic imaging of the human body, fluid visualization, 2D and 3D imaging, MR angiography and MR fluoroscopy.

This coil is intended to be used on the Atlas Vantage, model numbers MRT-1503/S3, /S4 and Atlas Titan, model number MRT-1504.

#### 7. Device Description

The Atlas SPEEDER Head/cervical is a phased Array Coil that can receive NMR signal from head, cervical region and upper chest.

OCT 1 7 2008

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

### Appendix A

The coil is configured in three sections; a head base, a removable anterior coil, and NV chest coil. There are two types of anterior coil; 1) Head anterior coil for head imaging, and 2) Neck anterior coil for cervical imaging. The Neck anterior coil includes an adjustable NV coil which is combined with Head anterior coil.

During transmission by the QD body coil this coil is deactivated by means of PIN diodes located on the internal circuit board. Upon deactivation of the transmit cycle the coil switches on to the receive mode.

#### Safety Parameter 8.

### Maximum static field strength

1.5 T

### Maximum dB/dt

1st operation mode specified in IEC60601-2-33 (2005)

### Maximum SAR

1st operation mode specified in IEC60601-2-33 (2005)

### Peak and A-weighted Acoustic Noise Level

Not applicable

### Biocompatibility

All materials used in contact with the patient will have a history of use or test data that demonstrates its biocompatibility, i.e., non-toxic, non-irritating.

#### 9. Imaging Performance Parameter

Sample phantom images and clinical images are presented in Appendix F & G.

#### 10. Equivalency Information

Toshiba Medical Systems Corporation believes that this Atlas SPEEDER Head/Cervical is substantially equivalent to the current Atlas SPEEDER Head [K063361] and SPEEDER 1.5T Wrist coil [K072935].

#### 11. Software

There is no additional software required for this coil.

### Dear Mr. Job:

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 such 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_
