VALUE PROPOSITION
For Magnetic Resonance Imaging it is often desirable to measure electrophysical characteristics alongside MRI data. To do so, voltage sensors are employed. This technology is an RF powered voltage sensor which can be configurable to measure a variety of physical indicators with excellent resolution. The design minimizes interference with MRI operations.
DESCRIPTION OF TECHNOLOGY
The parametric resonator is a circular-shaped loop-gap resonator with a continuous center conductor to bridge its virtual grounds. As a result, the resonator has a butterfly resonance mode at a lower frequency and a circular resonance mode at a higher frequency. When a pumping signal is applied at approximately the sum frequency of these two modes, the resonator can oscillate at frequencies that are close to the resonance frequencies of individual modes. Once the pumping signal is determined by an external frequency synthesizer, it will also determine the sum of butterfly and circular oscillation frequencies. If the butterfly mode oscillation signal falls within the detection band of the MRI scanner, it can be detected by a standard MRI coil allowing sensor information to be recorded.
