  • Patent number: 11320505
    Abstract: A method for magnetic resonance imaging uses an electromagnet [304], which may have open geometry, to generate a spatially nonuniform magnetic field within an imaging region [306]. The current through the electromagnet is controlled to repeatedly cycle the nonuniform magnetic field between a high strength for polarizing spins and a low strength for spatial encoding and readout. Using RF coils [308], excitation pulses are generated at a frequency that selects a non-planar isofield slice for imaging. The RF coils are also used to generate refocusing pulses for imaging and to generate spatial encoding pulses, which may be nonlinear. Magnetic resonance signals originating from the selected non-planar isofield slice of the nonuniform magnetic field in the imaging region [306] are detected using the RF coils [308] in parallel receive mode. MRI images are reconstructed from the parallel received magnetic resonance signals, e.g., using algebraic reconstruction.

  • Patent number: 11243284
    Abstract: A computer-implemented method for sequencing magnetic resonance imaging waveforms uses a multistage sequencing hardware. A method comprises creating, with the aid of a computer processor, an active memory region that includes waveforms and schedules being played, and creating one or more buffer memory regions that contain waveforms and schedules not currently being played. Next, the waveforms and schedules in the one or more buffer memory regions may be updated while waveforms may be played in the active memory region. Upon completion of the waveform playback in the active memory region, the active and buffer memory regions may be swapped so that the former buffer memory region becomes the active memory region, and the former active memory region becomes the buffer memory region. The method may be repeated as needed until the imaging process is completed or otherwise halted.

  • Patent number: 11189901
    Abstract: Example embodiments are directed to systems and methods for denying power to unauthorized power loads within a spherical waveguide bounded by the Earth's surface. One or more eigenmodes of the Earth-ionosphere waveguide may be computed based on a mathematical model incorporating electrical properties of the terrestrial surface and plasma physics of the ionosphere. A phased array of wave guide couplers, each including an array of electrically-connected waveguide-coupling elements, may be configured at different geographic locations for coupling to the one or more eigenmodes and generating standing waves in the Earth-ionosphere waveguide. Power loads may be detected via power reflections, and power nodes and nulls of the standing waves may be steered with respect to specified locations by adjusting relative phases and/or amplitudes of the waveguide couplers. Locations of power loads may be triangulating reflections. Power nulls of the standing waves may be steered to locations of unauthorized power loads.
