Intended Use

The dS Sentinelle Breast 16ch 1.5T Coil is intended to be used in conjunction with Philips 1.5T Magnetic Resonance Scanners to produce diagnostic images of the breast anatomy that can be interpreted by a trained physician. When used with a disposable biopsy grid, the device permits access to breast anatomy for biopsy and localization procedures.

Device Story

The dS Sentinelle Breast 16ch 1.5T Coil is a receive-only phased-array coil designed for use with Philips 1.5T MRI scanners. It captures magnetic resonance signals from hydrogen nuclei in breast tissue. The device features a variable coil geometry with three configurations (2, 10, or 16 channels) to optimize signal-to-noise ratio by positioning elements close to the breast. It includes a tabletop compression system to immobilize tissue and reduce motion artifacts. For interventional procedures, it integrates with a disposable biopsy grid to provide access to breast anatomy. The device is operated by trained clinicians in a clinical MRI environment. Output consists of diagnostic images (axial, sagittal, coronal, oblique) interpreted by a radiologist to support clinical decision-making, such as lesion detection or biopsy guidance.

Clinical Evidence

Bench testing included electrical/mechanical safety (IEC 60601-1), EMC (IEC 60601-1-2), image quality (NEMA MS-1, 3, 6, 9; IEC 62464-1), and biocompatibility (ISO 10993-1). Clinical performance was assessed by a U.S. Board Certified radiologist, who confirmed that images produced by the subject coils were of sufficient quality for diagnostic use.

Technological Characteristics

Receive-only phased-array coil; 1.5T magnetic field compatibility; 2/10/16-channel configurations; variable coil geometry; tabletop compression system; non-sterile, single-use biopsy grid. Complies with IEC 60601-1, IEC 60601-1-2, IEC 60601-2-33, NEMA MS-1/3/6/9, IEC 62464-1, and ISO 10993-1.

Indications for Use

Indicated for patients requiring diagnostic breast MRI or breast biopsy/localization procedures using Philips 1.5T MR scanners.

Regulatory Classification

Identification

| Device Description: | The dS Sentinelle Breast 16ch 1.5T Coil is a receive only coil to be used on a<br>70cm bore Philips Ingenia 1.5T MR System. The coil arrays are designed in a<br>magnetic strength (1.5T) to correspond with the scanner strength.<br>The dS Sentinelle Breast 16ch 1.5T Coil is a phased array design consisting of<br>patient support with three different coil configurations (2, 10 or 16 channels):<br>1. 16Ch for diagnostic imaging: performed in 16ch configuration that<br>consists of two dS Sentinelle Lateral 4Ch coils and the dS<br>Sentinelle Medial 8Ch coil.<br>2. 10Ch for bilateral interventional procedures requiring lateral<br>access: performed in 10Ch configuration that consists of the dS<br>Sentinelle Medical 8ch coil and two dS Sentinelle Lateral 1ch coils<br>(right and left).<br>3. 2Ch for unilateral interventional procedures allowing both lateral<br>and medial access: performed in 2Ch configuration that consists<br>of two dS Sentinelle Lateral 1Ch coils (right and left). | |
| | | |
| The coils receive magnetic resonance signals generated in hydrogen nuclei<br>(protons) in the Breast while blocking the high-frequency magnetic field<br>applied by the MRI scanner at specified timings. | | |
| The coil arrays include 4Ch right and left lateral coils, a medial coil and 1Ch<br>right and left lateral biopsy coils. | | |
| Images are typically generated as axial, sagittal, coronal and oblique slices and<br>include full coverage of the breast anatomy. | | |
| The dS Sentinelle Breast 16ch 1.5T Coil is tuned to receive RF frequency<br>corresponding to the proton precession in a 1.5 tesla magnetic field, which is<br>governed by the Larmor equation. | | |
| The Variable Coil Geometry design of the dS Sentinelle Breast 16ch 1.5T Coil<br>allows each imaging element to be independently positioned and configured<br>for each patient. Patients can then be positioned quickly and effectively as the<br>imaging elements can be positioned as close to the breast as possible<br>optimizing the signal-to-noise ratio for each individual patient. For clinical<br>imaging, coil housings are placed next to the tissue to help minimize motion<br>artifacts due to patient motion during scanning. | | |
| The subject dS Sentinelle Breast 16ch 1.5T Coil system also includes a<br>tabletop compression system which facilitates immobilization of the breast<br>for imaging and interventional procedures and serves to hold the individual<br>imaging coils in proximity to the breast(s). The intent of this is to reduce<br>motion artifacts and ensure the imaging elements are positioned as close to<br>the breast(s) as possible to optimize signal-to-noise ratio and image quality. | | |
| Indications for Use: | The dS Sentinelle Breast 16ch 1.5T Coil is intended to be used in conjunction<br>with Philips 1.5T Magnetic Resonance Scanners to produce diagnostic images<br>of the breast anatomy that can be interpreted by a trained physician. When<br>used with a disposable biopsy grid, the device permits access to breast<br>anatomy for biopsy and localization procedures. | |
| Fundamental<br>Scientific<br>Technology: | Based on the information provided above, the subject dS Sentinelle Breast<br>16ch 1.5T Coil is considered substantially equivalent to the primary currently<br>marketed and predicate device Sentinelle Breast MRI Tabletop with 16<br>Channel Coil Array for Siemens 1.5T/3T MRI Systems (K112112 – Aug 25,<br>2011) in terms of fundamental design, material and scientific technology. At a<br>high level the dS Sentinelle Breast 16ch 1.5T Coil and the predicate coil are<br>based on the following equivalent elements:<br>The same indications for usePrescription Use OnlyAnatomy of interest is the breastSame magnetic field strengths (1.5T)2/10/16-Channel configurations, receive only phased-array coil with<br>decoupling methodology | |
