MRI (Magnetic Resonance Imaging) systems are used to obtain a clear view of structures inside the body, non-invasively through applying the principal of nuclear magnetic resonance within a powerful magnetic field to image those structures, without the use of potentially harmful X-rays. An RF coil is used as an antenna, around the specific body part to be imaged. It communicates with the RF gradient within the magnetic field. That coil is typically connected into the MRI system with a high frequency cable and connectors.
Since components comprised of magnetic materials hold the potential to interfere with the image, these coil cables and connectors must be non-magnetic. Additionally, the signal, power, and RF contacts used in these connectors must be highly reliable for tens of thousands of mating cycles. However coaxial RF contacts can be large, costly, and fragile. As such, there is pressing need for smaller, more robust, and more cost efficient interconnect systems.
