Abstract: The present embodiments are directed towards the optical control of switching an electrical assembly. For example, in an embodiment, an electrical package is provided. The electrical package generally includes a micro electromechanical systems (MEMS) device configured to interface with an electrical assembly, the MEMS device being operable to vary the electrical assembly between a first electrical state and a second electrical state, a MEMS device driver in communication with the MEMS device and being operable to produce high voltage switching logic from an electrical signal, and an optical detector in communication with the MEMS device driver and configured to produce the electrical signal from an optical signal produced by a light source in response to an applied current-based electrical control signal.

Abstract: A system includes a multi-nuclear magnetic resonance (MR) receiving coil, wherein the receiving coil includes a frequency tuning component configured operate the receiving coil at either a first frequency or a second frequency. The receiving coil also includes an impedance matching component configured to maintain a substantially constant impedance of the receiving coil when the receiving coil is operated at either the first frequency or the second frequency. Furthermore, the receiving coil is configured to measure a first nucleus when operated at the first frequency, and wherein the receiving coil is configured to measure a second nucleus when operated at the second frequency.

Abstract: Embodiments of systems, methods, and non-transitory computer readable media for automatic landmarking are presented. A coil including at least one marker is placed on a desired region on interest (ROI) of a subject. Further, a detector detects a position of the marker while translating the subject from a home position in an imaging system into a bore of a magnet in the imaging system. A positioning unit coupled to at least one of the coil, the marker and the detector is configured to initiate automatic translation of the subject from the home position into the magnet bore. Further, the positioning unit determines a distance between the detected marker position and a homogenous position of the magnet based at least on the detected marker position. The positioning unit then controls movement of the subject over the determined distance to the homogenous magnet position for automatically landmarking the desired ROI.
