Intended Use

The 8ch Knee-Foot SPEEDER Coil is intended for use with Toshiba 1.5T MR systems to produce diagnostic images of the knee, wrist, hand, foot and ankle that can be interpreted by a trained physician.

Device Story

The 8ch Knee-Foot SPEEDER is a receive-only, 8-channel phased array RF coil for MRI. It captures magnetic resonance signals from the knee, wrist, hand, foot, and ankle. The device features a split-top mechanical design with interchangeable anterior pieces to accommodate different anatomies. It is used in clinical settings with Toshiba 1.5T MR systems. The coil is operated by MRI technicians or radiologists. The resulting images are displayed on the MR system console for interpretation by a physician to aid in clinical diagnosis. The device benefits patients by providing high-quality diagnostic images of the specified musculoskeletal regions.

Clinical Evidence

Clinical evidence consists of volunteer scanning of the knee, wrist, hand, foot, and ankle. Images were evaluated to demonstrate the device produces diagnostic quality images of the intended anatomies. No comparative statistical metrics (e.g., sensitivity/specificity) were required or reported.

Technological Characteristics

8-channel, receive-only, phased array RF coil. Rigid, flame/impact-resistant plastic housing. Biocompatible materials. Split-top mechanical design with interchangeable anterior pieces. Compatible with Toshiba 1.5T MR systems. Tested per AAMI/ANSI ES60601-1 and IEC 60601-2-33. Surface heating limit < 41°C. Bench testing per NEMA MS 6 and NEMA MS 9.

Indications for Use

Indicated for patients requiring diagnostic MRI imaging of the knee, wrist, hand, foot, and ankle using Toshiba 1.5T MR systems.

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.

#### 9. Device Description

The 8ch Knee-Foot SPEEDER coil is a receive-only, 8-channel phased array coil designed for magnetic resonance imaging (MRI) using the

{4}------------------------------------------------

Toshiba 1.5T MR systems. The 8ch Knee-Foot SPEEDER coil is intended to be used for imaging the knee, wrist, hand, foot and ankle.

The 8ch Knee-Foot SPEEDER coil is a reusable, non-invasive device with limited exposure with regard to duration of contact with the body. All coil elements are enclosed in a rigid plastic housing which is flame and impact resistant, and has been tested for biocompatibility.

The 8ch Knee-Foot SPEEDER coil also includes the comfort pads listed in Table 10-1, which are provided with the coil shipment.

#### 10. Indications for Use

The 8ch Knee-Foot SPEEDER Coil is intended for use with Toshiba 1.5T MR systems to produce diagnostic images of the knee, wrist, hand, foot and ankle that can be interpreted by a trained physician.

The Indications for Use statement for the 8ch Knee-Foot SPEEDER coil is not identical to that of the predicate device; however, the differences do not alter the intended diagnostic use of the device nor do they affect the safety and effectiveness of the device relative to the predicate. The proposed 8ch Knee-Foot SPEEDER coil is a modification to the predicate 8ch Knee SPEEDER coil that expands the intended use from knee, wrist, hand and forefoot to knee, wrist, hand, foot and ankle; thereby encompassing the whole foot and ankle. This is accomplished by adding a second anterior piece used for foot and ankle imaging. The posterior and knee anterior piece remain identical to the predicate 8ch Knee SPEEDER coil cleared under K152695.

### 11. Summary of Technological Characteristics Compared to the Predicate Device

At a high level, the subject and predicate devices are based on the following same technological elements:

{5}------------------------------------------------

- Intended to provide images of the knee, wrist and hand regions ●
- 8-channel, receive-only, phased array RF coils
- . Split-top mechanical design
- . Housing materials are flame, impact resistant and biocompatible
- Knee, wrist, and hand imaging accomplished through 8ch Knee ● SPEEDER configuration
- Compatible with Toshiba 1.5T MR systems ●

The following technological differences exist between the subject and predicate device:

- Intended to provide images of the foot and ankle regions (subject) . versus forefoot region (predicate) in addition to knee, wrist and hand
- Two anterior pieces with split-top mechanical design shaped to fit . the knee and foot (subject) versus single split-top mechanical design shaped to fit the knee (predicate)

#### 12. Performance Data

The following performance data were provided in support of the substantial equivalence determination.

## Biocompatibility Testing

All surface materials on the 8ch Knee-Foot SPEEDER coil that are intended to come into direct or indirect contact with patient biological tissues, cells or body fluids have a history of safe use in previouslycleared devices.

## Electrical Safety and Electromagnetic Compatibility

The electrical safety and electromagnetic compatibility of the 8ch Knee-Foot SPEEDER coil was verified in accordance with AAMI/ANSI ES60601-1 and IEC 60601-2-33.

Surface heating was tested in accordance with AAMI/ANSI ES60601-1. The measured temperature of the surface of the coil never exceeded the maximum limit of 41°C.

## Performance Testing - Bench

{6}------------------------------------------------

The SNR and uniformity of the 8ch Knee-Foot SPEEDER was analyzed per NEMA MS 6 and NEMA MS 9 and was found to conform to predetermined acceptance criteria.

## Performance Testing - Clinical

In accordance with the FDA Guidance for Industry: Guidance for the Submission of Premarket Notifications for Magnetic Resonance Diagnostic Devices, clinical images from volunteer scanning of the knee, wrist, hand, foot and ankle were obtained from the 8ch Knee-Foot SPEEDER. These images were used to demonstrate that the 8ch Knee-Foot SPEEDER produces diagnostic quality images of the intended anatomies.

#### 13. Conclusion

The electrical safety and electromagnetic compatibilitv and biocompatibility data support the safety of the 8ch Knee-Foot SPEEDER and the bench testing per the NEMA standards demonstrates the performance and effectiveness of the device under the specified use conditions. This testing demonstrates that the 8ch Knee-Foot SPEEDER performs as well as or better than the predicate device.
