Intended Use

The Siemens Magnetom CP Breast Array Coil is indicated for use as a diagnostic imaging device accessory to produce transverse, saggital, coronal and oblique images of the internal structures of the breast.

Device Story

CP Breast Array Coil functions as a receiver coil accessory for Siemens Magnetom Harmony and Symphony MRI systems. Device captures radiofrequency signals from breast tissue to produce diagnostic images in transverse, sagittal, coronal, and oblique planes. Used in clinical radiology settings by trained MRI technologists/physicians. Output images are viewed by radiologists to assess internal breast structures. Device enhances signal-to-noise ratio (SNR) and image uniformity compared to standard configurations, aiding in diagnostic visualization.

Clinical Evidence

Bench testing and clinical evaluation performed. Bench testing included measurements of signal-to-noise ratio (SNR) and image uniformity. Clinical testing demonstrated the device's ability to produce diagnostic quality images of internal breast structures in multiple planes. No specific statistical metrics (e.g., p-values, sensitivity) were reported in the summary.

Technological Characteristics

Receiver coil for MRI systems. Designed for use with Magnetom Harmony and Symphony. Passive RF coil array. No internal energy source; operates as part of the MR system's RF receive chain. Connectivity is via proprietary interface to the Magnetom system.

Indications for Use

Indicated for use as a diagnostic imaging device accessory to produce transverse, saggital, coronal and oblique images of the internal structures of the breast.

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.

# II. Safety and Effectiveness Information Supporting Substantial Equivalence.

# · Device Description:

The CP Breast Array Coil is a receiver coil for the Magnetom Harmony and Symphony

#### •Intended Use

The Siemens Magnetom CP Breast Array Coil is indicated for use as a diagnostic imaging device accessory to produce transverse, saggital, coronal and oblique images of the internal structures of the breast.

# • Technological Characteristics

The magnet, RF system, and gradient system, of the MAGNETOM Harmony and Symphony configured with the CP Breast Arrav Coil is substantially equivalent to the standard MAGNETOM Harmony and Symphony system.

# · General Safety and Effectiveness Concerns:

Operation of the MAGNETOM Harmony and Symphony system with the new CP Breast Array Coil is substantially equivalent to standard operation of the MAGNETOM Harmony and Symphony system. The following safety parameter action levels:

- static field strength, r
- RF exposure, ।

and performance levels:

- high contrast spatial resolution, ।
- slice thickness, and -
- geometric distortion -

specified by the FDA guidance document for MR Diagnostic Devices are unaffected by the modifications described within this notification. Additional SNR and image uniformity measurements were performed for the new imaging coil & presented in this documentation.

## · 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 Ms. Rutherford:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have desemined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in internate commerce prior to May 28, 1976, the ensement date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Pederal Food, Drug, and Cometic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against mistoranion.

If your device is classified (see above) into class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Cade of Enderal Regulations. Title 21, Pars 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice r - wirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Polenal Register. Places note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
