Electrically Isolated Power Delivery for MRI Applications
Wu T, Werthen J, Widjaja S, Cohen M
Photonic power, a means of converting laser light over fiber into electric power, offers several advantages compared to copper in powering electronics in high magnetic fields. Photonic power is a fully-isolated, non-conductive means of powering imaging coils, control electronics, and video monitors in MR systems. Advantages include improved noise immunity, enhanced imaging, reduced risk of patient RF burns, and more reliable patient surveillance techniques. This paper will describe the implementation of this technology for use in a broad array of applications in the MRI environment.
