designed to provide optimum signal-to noise, uniform coverage
and high acceleration including multiband imaging of the head
and brain. It is a 48-element coil tuned to image proton nuclei
and designed for use with GE 3.0T MRI Systems. Each coil
element has an integrated preamplifier to improve image
quality. The 48CH Head Coil has an anterior coil and a
posterior coil with P-connectors. The coil has optimized pads to
maximize patient comfort and image uniformity. | | Intended Use: | The 3.0T 48CH Head Coil is a receive-only RF coil designed
for use with select 3.0T MRI systems manufactured by GE
Healthcare. The coil is indicated for use for head imaging. The
nucleus excited is hydrogen. | | Comparison of Intended Use: | The intended use statements are identical. | | Comparison of Technological
Characteristics: | The 48CH Head Coil employs the same fundamental scientific
technology as its predicate device.

Coil Design: The 48CH Head Coil design is the same as the
predicate device but implements a design change to the
decoupling circuit.

Operating Principles: The 48CH Head Coil operates on the
same principles as the predicate device.

Materials: The 48CH Head Coil uses the same materials as the
predicate device.

Safety and Performance Testing: The 48CH Head Coil
complies with the same safety and performance testing as the
predicate device.

These technological differences do not raise any different
questions of safety and effectiveness. | | Determination of Substantial
Equivalence: | Summary of Non-Clinical Tests:

The predicate and modified devices have been subject to the
same risk management testing to demonstrate substantial
equivalence of safety and performance.

Testing included: AAMI/ANSI ES60601-1 IEC 60601-1-2 IEC 60601-2-33 MS6-2008 Maximum B1 Peak Blocking Network Analysis Surface Temperature Testing The predicate and modified devices use the same patient
| {4}------------------------------------------------ {5}------------------------------------------------ | Summary of Clinical Tests: | The subject of this premarket submission, the 48CH Head Coil, did not require clinical studies to support substantial equivalence. | |--------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | Substantial Equivalence Conclusion: | The indications for use of the proposed device are identical to the claimed predicate device. The 48CH Head Coil employs equivalent technology to the claimed predicate device. Additionally, the results from the above non-clinical tests demonstrate that the device performs as intended. Thus, the 48CH Head Coil is substantially equivalent to the predicate device to which it has been compared. | | Conclusion: | GE Healthcare considers the 48CH Head Coil to be as safe and effective, and performs in a substantially equivalent manner to the predicate device. | --- **Source:** [https://fda.innolitics.com/submissions/RA/subpart-b%E2%80%94diagnostic-devices/MOS/K180666](https://fda.innolitics.com/submissions/RA/subpart-b%E2%80%94diagnostic-devices/MOS/K180666) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
