#### Safety and Effectiveness Information Supporting Substantial Equivalence

#### Indications for Use

The 16Ch Diagnostic Breast Coils are indicated for use as diagnostic imaging device extensions for GE 1.5 T MR Systems and GE 3.0 T MR Systems to produce transverse, sagittal, coronal and oblique images, spectroscopic images and/or spectra, and that display the internal structure of the breast. These images when interpreted by a trained physician yield information that may assist in diagnosis.

#### Device Description

The 16Ch Diagnostic Breast Coil (1.5 T 16Ch Diagnostic Breast Coil and 3.0 T 16Ch Diagnostic Breast Coil) is designed for use with a magnetic resonance (MR) system. The coil is designed to work in unison with the Body Coil (BC) of the MR system, which will excite the hydrogen (1H) nuclei with radio frequency (RF) magnetic fields, so that the coil may receive the resultant RF signal from the excited nuclei. The coil is designed as a receive-only coil for high resolution MR examination of breast.

The coil housing features a curved surface for better adaption to the anatomical region of interest. The coil is receive-only (Rx) and consists of 16 independent single loop coil elements with integrated low noise preamplifiers and a connector to the GE 1.5 T MR Systems or the GE 3.0 T MR Systems. The coil is fixed tuned and matched to the typical load of a breast at the Larmor frequency of 1H at 1.5 T (63.9 MHz) or 3.0 T (127.7 MHz) respectively. Decoupling circuits are integrated in each single loop element providing a decoupling from the Body Coil of the MR System during transmission of the RF excitation pulse. The coil provides both, unilateral and bilateral images (Left, Right and Both) of the anatomy of interest.

#### Equivalency Information

RAPID Biomedical believes that the Subject Device is substantially equivalent to the cleared Predicate Device which is described in the following submission.

| Predicate Device Name | Clearance Number | Date |
|--------------------------------------------------------|------------------|------------|
| 16ch Al Breast Coil 1.5T and 16ch Al<br>Breast Coil 3T | K083255 | 2008-11-21 |

#### Summary of Technological Characteristics of the Subject Device as compared with the Predicate Device

The proposed labelling is adjusted compared to the predicate device with respect to differing MR Systems, changes in the currently applicable standards and for better usability.

Overall, the indications for use, the intended use and the coil technology and safety are substantially equivalent.

#### General Safety and Effectiveness Concerns

The safety and performance parameters according to the FDA Guidance Document "Submission of Premarket Notifications for Magnetic Resonance Diagnostic Devices, issued on Nov. 18, 2016" are unaffected by the modifications described within this notification.

#### Nonclinical Tests

Nonclinical tests were performed on a loading phantom to evaluate the subject device concerning applicable imaging parameters Signal to Noise Ratio (SNR) and Image Uniformity. Test were conducted following NEMA Standards. Test results show an enhanced SNR performance of the subject device, while determined Image Uniformity compares well to the results from the predicate device.

The subject device is conforming to:

- AAMI / ANSI ES60601-1:2005/(R)2012 and A1:2012, c1:2009/(r)2012 and . a2:2010/(r)2012 (consolidated text) medical electrical equipment - part 1: general requirements for safety and essential performance (iec 60601-1:2005, mod). (General II (ES/EMC)). FDA Recognition number: #19-4
- IEC 60601-2-33 Ed. 3.1:2013, medical electrical equipment part 2-33: particular . requirements for the basic safety and essential performance of magnetic resonance equipment for medical diagnosis. (Radiology). FDA Recognition number: #12-271
- NEMA Standards Publication MS 6-2008 (R2014) Determination of Signal-to-Noise . Ratio and Image Uniformity for Single-Channel Non-Volume Coils in Diagnostic MR Imaging. FDA Recognition number: #12-195
- NEMA Standards Publication MS 9-2008 (R2014) Standards Publication 0 Characterization of Phased Array Coils for Diagnostic Resonance Images. FDA Recognition number: #12-288

All safety tests were performed on GE MR Systems. The test results are approved by GE for proving the full system compatibility.

#### Clinical Tests

Clinical tests were performed on volunteers in order to check image quality in vivo. Typical sequences for diagnosis were applied (Vibrant, DWI, CUBE T2-flex, FSE T2 with Aspir, FSPGR-T1) with standard scan parameters and image orientations (axial and sagittal). Clinical test show that the subject device provides adequate image quality (SNR, penetration depth, contrast, resolution and robustness against artifacts) as well as scan time and patient comfort are good.

Sample clinical images (Dicoms) are provided as part of the discussion of the clinical tests submitted.

### Conclusion as to Substantial Equivalence

Testing was performed to support this claim of substantial equivalence and to show that the modifications do not raise any new questions pertaining to safety and effectiveness.

The modifications did not affect the Indications for Use, the Intended Use and did not alter the Fundamental Scientific Technology.

RAPID Biomedical therefore believes the subject devices and the Predicate Devices to be substantially equivalent (SE).
