摘要： A magnetic field generator includes a power source and a segmented or un-segmented coil connected to the power source to generate a time-varying magnetic field. Energy is applied to the coil so that the coil generates a time-varying magnetic field gradient with a magnitude of at least 1 milliTesla per meter and a rise-time of less than 10 microseconds. The coil may be comprised of overlapping, non-overlapping or partially overlapping coil segments that may individually energized to further improve the operating characteristics of the coil to further decrease bio-effects in magnetic resonance imaging through the use of reduced pulse lengths and multi-phasic magnetic gradient pulses.

摘要： An electromagnetic structure is fabricated by additive manufacturing having at least one channel traversing the structure. In one embodiment, at least one form contains apertures and/or holes forming the channel and a liquid metal traverses the structure by the channel. Electrodes are provided to apply or extract electrical voltage or power to and/or from the liquid metal as well as a mechanism for propelling a portion of the liquid metal through the form. In an alternative embodiment, both the electrically insulating and the electrically conductive materials are solid and the channel is used for conducting a coolant instead of the liquid metal.
