  • Point-of-care magnetic resonance imaging system for lumbar puncture guidance
    Patent number: 12290323
    Abstract: A single-sided magnet and magnetic resonance imaging (“MRI”) system are portable and lightweight, enabling use as a point-of care (“POC”) MRI device. The portable MRI system includes a magnet assembly containing layers of magnet blocks, such as rare-earth magnet blocks. The magnet blocks are arranged in concentric rings in each layer, and surround a central aperture extending through the magnet assembly. The central aperture is sized to allow a medical instrument, such as a needle, to pass through the central aperture. The portable MRI system can therefore be used for image guidance in lumbar puncture (“LP”) and other medical procedures.

  • Asymmetric single-channel radio frequency helmet coil for magnetic resonance imaging
    Patent number: 12270872
    Abstract: Asymmetric, single-channel radio frequency (“RF”) coils are provided for use with portable or other low-field magnetic resonance imaging (“MRI”) systems. In general, the asymmetric, single-channel RF coils make use of asymmetric, optimized winding configurations in order to reduce B1+ inhomogeneities and to reduce signal sensitivity outside of the desired imaging field-of-view (“FOV”).
